Impact abrasive wear of tungsten carbide reinforced NiBSi coating fabricated by plasma transferred arc welding
The development of spherical cast eutectic WC/W2C (WCSC) reinforced Ni alloy coatings is limited by insufficient understanding of the microstructure evolution and its impact on abrasive wear behavior, which makes it challenging to enhance wear performance through microstructure control. In this study, NiBSi alloy coating reinforced by WCSC particles was prepared using plasma transferred arc welding (PTAW) technology. The microstructure of the coating was characterized using XRD, SEM, LCM, and TEM analysis. The results show that a large number of secondary carbides identified as W2C, M6C, and M4C were generated due to the partial dissolution of WCSC in the Ni-based molten pool. Two kinds of eutectics formed in the matrix were determined to be γ-Ni + M6C and γ-Ni + Ni3B. The microstructure evolution mechanism was revealed with the aid of EPMA analysis and CALPHAD-type calculations. The microhardness of the matrix was increased by dispersion strengthening and solid solution strengthening. The impact abrasive wear performances were analyzed using the MLD-10 wear tester, and the maximum impact wear mass loss of coating was observed at an impact energy of 3 J. At an impact energy of 1 J, furrow-type wear and fatigue wear are the main wear mechanisms of the coating. WCSC particles can effectively prevent the cutting of the matrix by abrasive particles. With the increase of impact energy to 3 J, the wear mechanism of the coating is mainly dominated by the fatigue wear and spalling pits of the matrix, as well as the fatigue and spalling of the WCSC particles and secondary carbides. At a high impact energy of 5 J, the fragmentation and spalling of the WCSC particles were generated, and massive spalling pits existed in the matrix. It is suggested that the control of the degradation of the WCSC particles should be focused on in future research.
期刊介绍:
Surface and Coatings Technology is an international archival journal publishing scientific papers on significant developments in surface and interface engineering to modify and improve the surface properties of materials for protection in demanding contact conditions or aggressive environments, or for enhanced functional performance. Contributions range from original scientific articles concerned with fundamental and applied aspects of research or direct applications of metallic, inorganic, organic and composite coatings, to invited reviews of current technology in specific areas. Papers submitted to this journal are expected to be in line with the following aspects in processes, and properties/performance:
A. Processes: Physical and chemical vapour deposition techniques, thermal and plasma spraying, surface modification by directed energy techniques such as ion, electron and laser beams, thermo-chemical treatment, wet chemical and electrochemical processes such as plating, sol-gel coating, anodization, plasma electrolytic oxidation, etc., but excluding painting.
B. Properties/performance: friction performance, wear resistance (e.g., abrasion, erosion, fretting, etc), corrosion and oxidation resistance, thermal protection, diffusion resistance, hydrophilicity/hydrophobicity, and properties relevant to smart materials behaviour and enhanced multifunctional performance for environmental, energy and medical applications, but excluding device aspects.
