The effect of micro-blasting on the tribological properties of TiN/MT-TiCN/Al₂O₃/TiCNO coatings was studied. The multilayer coatings were deposited on cemented carbides by chemical vapor deposition. The microstructure, mechanical and tribological properties were investigated using X-ray diffraction, scanning electron microscopy (SEM), nano-mechanical testing system, scratch tester and reciprocating tribometer. The results show that micro-blasting significantly reduces the surface roughness and converts the residual tensile stress of Ti(C,N,O) top-layer and Al₂O₃ layer into compressive stress. Affected by the residual compressive stress, the hardness and adhesion strength are increased. More importantly, the friction coefficient is decreased attributed to the decreased surface roughness and improved hardness. Also, the wear resistance of micro-blasted TiN/MT-TiCN/Al₂O₃/TiCNO is superior due to higher hardness of Ti(C,N,O) top-layer, Al₂O₃ layer and adhesion strength of coatings. Especially for the total sliding time of 2 h, the wear volume and wear rate of micro-blasted coatings are 69.4% of as-deposited coatings, because micro-blasting helps to increase the adhesion strength and micro-cracking resistance, which play important roles in the improvement of wear resistance. Micro-blasting has a positive effect on the friction and wear properties of TiN/MT-TiCN/Al₂O₃/TiCNO multilayer coatings since the adverse impact of top-layer thinning is offset.

研究了微喷处理对TiN / MT-TiCN / Al ₂ O ₃ / TiCNO涂层的摩擦学性能的影响。通过化学气相沉积将多层涂层沉积在硬质合金上。使用X射线衍射，扫描电子显微镜（SEM），纳米机械测试系统，划痕测试仪和往复式摩擦计对显微组织，力学和摩擦学性能进行了研究。结果表明，微喷处理可显着降低表面粗糙度并转化Ti（C，N，O）顶层和Al ₂ O ₃的残余拉伸应力层变成压缩应力。受残余压应力的影响，硬度和粘合强度增加。更重要的是，摩擦系数的降低归因于表面粗糙度的降低和硬度的提高。此外，由于Ti（C，N，O）顶层Al ₂ O _3的硬度较高，因此微喷TiN / MT-TiCN / Al ₂ O ₃ / TiCNO的耐磨性优异。涂层的附着力和强度。特别是对于总滑动时间为2 h而言，微喷涂层的磨损量和磨损率为沉积态涂层的69.4％，因为微喷有助于提高附着强度和抗微裂纹性，这起着重要作用在提高耐磨性方面。微喷丸对TiN / MT-TiCN / Al ₂ O ₃ / TiCNO多层涂层的摩擦磨损性能具有积极影响，因为可以抵消顶层减薄的不利影响。
