Abstract The objective of the present work is focused towards the reduction of wear in industrial applications. This can be overcome by applying layers of the protective coatings on the surface of the substrate, thereby improving surface properties. Here in the present work three powders WC-12%Co, NiCrBSi, Cr3C2–25wt%NiCr are taken, from which three types of blended powders are prepared taking in proper wt% by means of mechanical blending. The powders prepared are (30wt%WC Co12+70wt%NiCrBSi), (30wt%WC -Co12+70wt%Cr3C2 NiCr25) and (30wt%WC Co12+ 35wt%NiCrBSi+35wt%Cr3C2 NiCr25). These powders are sprayed using High Velocity Oxy Fuel (HVOF) process on to the substrate. The coatings are tested for mechanical and tribological properties. From the results found, the blend of (30wt%WC Co12+70wt%NiCrBSi) showed good wear resistance and NiCrBSi as minimum Coefficient of Friction. Multiobjective optimization was done and the blend of WC Co and NiCrBSi was found to exhibit superior results at high temperature (3500C), high load (30 N) and for the distance of (15,000 m).

摘要 目前工作的目标是减少工业应用中的磨损。这可以通过在基材表面上施加保护涂层层来克服，从而改善表面性能。在目前的工作中，采用了三种粉末 WC-12%Co、NiCrBSi、Cr3C2-25wt%NiCr，通过机械混合的方式制备了三种类型的混合粉末，以适当的 wt%。制备的粉末为（30wt%WC Co12+70wt%NiCrBSi）、（30wt%WC-Co12+70wt%Cr3C2 NiCr25）和（30wt%WC Co12+35wt%NiCrBSi+35wt%Cr3C2 NiCr25）。这些粉末使用高速氧燃料 (HVOF) 工艺喷涂到基材上。测试涂层的机械和摩擦学性能。从发现的结果来看，(30wt%WC Co12+70wt%NiCrBSi) 的混合物表现出良好的耐磨性，NiCrBSi 作为最小摩擦系数。进行了多目标优化，发现 WC Co 和 NiCrBSi 的混合物在高温 (3500C)、高负载 (30 N) 和距离 (15,000 m) 下表现出优异的结果。
