摘要
电子显微镜和 X 射线衍射分析用于研究通过非真空电子束包覆 TiC 和 Ti + C 粒子在 12Kh18N9T 钢上沉积的涂层结构。在与固定磨料颗粒摩擦和水磨冲击的条件下，对涂层样品进行了磨损测试。结果表明，Ti + C 混合粉末的包覆产生了以树枝状结构为主的复合碳化钛。用 TiC 颗粒加固 12Kh18N9T 钢（AISI 321）的表层可使其耐磨性加倍。
Raising the Wear Resistance of Chromium-Nickel Steel Surface-Hardened with Titanium Carbide Particles
Electron microscopy and x-ray diffraction analysis are used to study the structure of coatings deposited on steel 12Kh18N9T by non-vacuum electron beam cladding of TiC and Ti + C particles. Wear tests of the coated samples are performed under the conditions of friction against fixed abrasive particles and hydroabrasive impact. It is shown that cladding of the Ti + C powder mixture produces composite titanium carbides with dominantly dendritic structure. The reinforcement of the surface layers of steel 12Kh18N9T (AISI 321) with TiC particles doubles its wear resistance.
