B_4C-Mo和TiC-W两种金属陶瓷涂层的性能研究

Performance Study for B_4C-Mo and TiC-W Coatings

应用 Co的溅射原理 ,以磁控管溅射低温沉积法在轴承钢 Gr15 (2 0 mm×5 mm)基体上分别制备了 B4 C- Mo和 Ti C- W金属陶瓷涂层。然后测量了涂层的粘附力、强韧性和抗滑动摩擦性。实验表明 :Ti C- W涂层具有高的耐磨性 ;B4 C- Mo涂层具有较高的硬度 (>5 0 0 0 HKN)

Using a similar approach, two different carbide-metal cermet systems were fabricated in coating-form using bias-assisted unbalanced magnetron Co-sputtering from a single target.Cermet systems that were fabricated for subsequent evaluation included boron carbide(B 4C)-molybdenum(Mo)and titanium carbide (TiC)-tungsten(W).Then scratch adhesion,micro hardness,and wear tests were performed to enable performance analysis between the different cermet systems.In general, unique performances were measured for the different cermet systems.For example,the TiC-W system exhibits excellent wear resistance,whereas the B 4C-Mo system has extremely high hardness(>5000 HKN).
