The metal plastic flow regularities experimental estimation, as well as the residual stresses (RS) values in the treatment processes is an important task to correctness justification of obtained finite element modeling solutions. However, the currently known and used plastic flow regularities and RS experimental determination methods in most cases have a significant disadvantages: labor intensity, low accuracy, sample preparation necessity and difficult to apply on real parts. This work purpose is to develop special equipment and methods for researches by the digital image correlation method for conducting experimental metal plastic flow and RS researches during free orthogonal cutting and surface plastic deformation (SPD) under the technological treatment factors variation. The paper substantiates orthogonal loading schemes in the metal plastic flow research in the cutting and SPD processes, research accessories and equipment is developed. The machine movement errors were determined, the sample sizes and loading routines were determined and justified. Using the digital image correlation method, the metal plastic flow experimental researches in the deformation zone during free orthogonal cutting and surface plastic deformation processes were performed. For experimental samples RS determinination after free orthogonal cutting and surface plastic deformation, the digital image correlation and probing hole drilling methods combination was used for the first time, which idea is to determine the material particles movements on the sample top from two images: the sample surface having residual stresses and the same surface after high-speed probing hole.
金属塑性流动规律的实验估计,以及处理过程中的残余应力(RS)值是获得有限元建模解正确性论证的重要任务。然而,目前已知和使用的塑性流动规律和RS实验测定方法在大多数情况下存在劳动强度大、精度低、需要制样、难以应用于实际零件等显著缺点。本工作的目的是开发专用的设备和方法,通过数字图像相关方法进行实验金属塑性流动和RS研究在自由正交切割和表面塑性变形(SPD)的工艺处理因素的变化。研究了正交加载方案在切削和SPD过程中金属塑性流动的研究,开发了研究附件和设备。确定了机器的运动误差,确定了样品大小和装载程序并进行了验证。采用数字图像相关方法,对自由正交切削和表面塑性变形过程中变形区金属塑性流动进行了实验研究。在自由正交切割和表面塑性变形后的实验样品RS测定中,首次采用了数字图像相关和打孔打孔方法相结合的方法,其思路是从具有残余应力的样品表面和高速打孔后的样品表面两幅图像中确定样品顶部的材料颗粒运动。

Studies of the deposited layer obtained using flux-cored wires of the Fe—C—Si—Mn—Cr—W—V system by introducing titanium and carbon-fluorine-containing material into their composition — gas cleaning dust of aluminum production, wt.%: 21...46 Al2O3; 18...27 F; 8...15 Na2O; 0.4...6 K2O; 0.7...2.3 CaO; 0.5...2.5 SiO2; 2.1...3.3 Fe2O3; 12.5...30.2 CTotal; 0.07...0.9 MnO; 0.06...0.9 MgO; 0.09...0.19 S; 0.10...0.18 P. The deposited layer was obtained using submerged arc surfacing by the ASAW-1250 welding tractor using a fabricated flux-cored wire made from slag produced by silicomanganese with a chemical composition, mass. %: 0.50 FeO; 15.16 MnO; 29.13 CaO; 42.40 SiO2; 6.80 Al2O3;1.39 MgO; 0.18 Na2O; 0.59 K2O; 0.28 S; 0.022 P; 0.004 ZnO; 0.024 C; 0.32 F; 0.17 TiO2; 0.033 Cr2O3. The studies carried out made it possible to establish the relationship between the chemical composition of the deposited flux-cored wire and the structure and properties of the deposited metal. It has been established that the introduction of titanium increases the values of hardness and microhardness. The use of a carbon-fluorine-containing additive leads to microstructural changes expressed in obtaining the structure — ferrite, perlite and bainite, in contras t to the structure — martensite, δ-ferrite and residual austenite, as well as to an increase in the size of martensite needles in the structure of the deposited layer. Microstructural changes are due to the introduction of a carbon fluorine-containing additive into the composition of flux-cored wire and are accompanied by a change in microhardness and hardness. With an increase in the content of the carbon-fluorine-containing additive in the composition of flux-cored wire, an increase in the microhardness and hardness of the deposited metal is observed.
在Fe-C-Si-Mn-Cr-W-V系焊丝中引入钛和含碳氟物质制备沉积层的研究——铝生产气体净化粉尘,wt %: 21…46氧化铝;18…27F;8…15Na2O;0.4……6K2O;0.7曹…2.3;0.5……2.5二氧化硅;2.1, 3.3 Fe2O3;12.5, 30.2 CTotal;0.07……0.9 MnO;0.06……0.9分别;0.09……0.19秒;采用化学成分为质量的硅锰渣制成的药芯焊丝,在ASAW-1250焊接拖拉机上采用埋弧堆焊获得了堆焊层。%: 0.50 FeO;15.16 MnO;29.13曹;42.40二氧化硅;6.80 Al2O3;1.39 MgO;0.18 Na2O;0.59 K2O;0.28年代;0.022便士;0.004氧化锌;0.024摄氏度;0.32 F;0.17二氧化钛;0.033 Cr2O3。所进行的研究使人们能够确定所沉积的药芯焊丝的化学成分与所沉积金属的结构和性能之间的关系。结果表明,钛的加入提高了合金的硬度和显微硬度。含碳氟添加剂的使用导致微观组织变化,表现为获得组织-铁素体、珍珠岩和贝氏体,而不是组织-马氏体、δ-铁素体和残余奥氏体,并使沉积层组织中的马氏体针状体尺寸增加。微观结构的变化是由于在药芯焊丝的成分中加入了含氟碳的添加剂,并伴随着显微硬度和硬度的变化。随着药芯焊丝成分中含碳氟添加剂含量的增加,观察到沉积金属的显微硬度和硬度增加。

In the presented article it was studied the structure and the properties of the C-Ag coating electrical explosion sprayed on copper substrate. It was found that obtained coating, from 7...200 µm thick, has complex relief. Graphite is represented as plate shape structures and sub-nanosized globular particles. There are also copper oxide particles in the coating. A transition area with a thickness of 100...150 nm, which has a complex structure, is formed on the boundary between the coating and the substrate. The silver grains in the coating have a platelet structure, and the copper substrate has a subgrain structure. The hardness and Young's modulus of the "coating (Ag-C)/(copper) substrate" system increase with the distance from the surface to the boundary between the coating and the substrate. The coating wear parameter is 2.3 times less compared to the copper substrate. The coating friction coefficient is equal to the substrate friction coefficient.

The surface plastic deformation of structural steels was studied using ultrasound. Four variants of hardening are considered: ultrasonic treatment with continuous supply of ultrasonic energy, pulsed ultrasonic treatment, a combination of ultrasonic treatment followed by pulsed treatment, and ultrasonic treatment after quenching with induction heating. It is shown that UST increases the microhardness of the surface layer of structural steels by 1.5 times, HFC hardening by more than 2 times, combinations of HFC hardening + UST by 3 times, and HFC + UST hardening by 3.2 times. Ultrasonic treatment increases the compressive stresses that occur in the steel surface hardened by HFC hardening. Compressive stresses increase especially strongly after pulsed ultrasonic treatment with five passes and reach a value of 1200 MPa.

A test for resistance to gas-abrasive wear of several variants of multilayer vacuum-plasma coatings based on titanium and vanadium nitrides of various thicknesses and number of layers was carried out. Erosion curves are given, areas of accelerated wear are determined, and comparative values of wear resistance are calculated. Based on the conducted microscopic studies, a mechanism of layer-by-layer wear of the studied multilayer coatings is proposed. It is shown that due to the creation of a special layered coating structure, including the alternation of highly hard nitride and relatively softer Ti and V layers, the resistance to gas-abrasive wear of parts of gas turbine engines made of titanium alloys is greatly increased.

The results of an analytical study of the walking mechanisms of dragline excavators are presented. The advantages and disadvantages of the hydraulically driven walking mechanism are considered. Constructive changes are proposed in the form of installation of sliding supports and horizontal arrangement of traction hydraulic cylinders on support shoes. A method for calculating the forces acting on sliding bearings is presented, which makes it possible to determine the requirements for the physical and mechanical properties of the sliding bearings material, including the hardness and wear resistance of their working surfaces. Examples of using the mathematical model of a three-bearing walking mechanism with sliding supports, created in the MATLAB Simulink software environment, are shown.

The results of testing the "brass" type coating under conditions of oil lubrication I-20A with additives of the metal-coating additive "Valena" at a specific pressure of up to 130 MPa are presented. It is shown that additives have no effect on the wear intensity, which is in the range of (0.5...12.0)•10–9 in the load range 314...1882 N. The influence of the phase composition on the tribological properties of the coating and recommendations on the technological parameters of spraying and testing are evaluated.
介绍了在I-20A油润滑条件下,添加金属涂层添加剂“Valena”,在高达130 MPa的比压下对“黄铜”型涂层的测试结果。结果表明,添加剂对磨损强度无影响,在314 ~ 1882载荷范围内,磨损强度在(0.5 ~ 12.0)~ 10 ~ 9之间N.评估了相组成对涂层摩擦学性能的影响以及对喷涂和测试技术参数的建议。
