Friction surfacing is a solid-state coating process that uses plastic deformation to improve the efficiency of the core metallic pattern, resulting in fine-grained coatings with superior wear and corrosion properties. This article focuses on the development of inherently homogeneous, non-diluted coating of AISI316Ti stainless steel above EN8 and also encloses the empirical relationship for the prediction of bond strength (B), coating thickness (C), and coating width (C). The key individualities for bonding geometry were believed to be the process parameters such as rotational speed (rpm), traverse speed (mm/s), and axial load (kN). The effect of input parameters on the bond's external dimensions and strength was investigated using a multi-objective optimization approach through experimentation. The bond's strength improved as the coating thickness was reduced and the coating width was increased. The grain-refined coatings superimposing martensitic microstructure with no deposition of carbide particles added value to the metallurgical study using the scanning electron microscope.
摩擦堆焊是一种固态涂层工艺，它利用塑性变形来提高核心金属模式的效率，从而得到具有优异耐磨和耐腐蚀性能的细晶涂层。本文着重研究了高于EN8标准的AISI316Ti不锈钢固有均匀、非稀释涂层的开发，并给出了预测结合强度（B）、涂层厚度（C）和涂层宽度（W）的经验关系。认为结合几何形状的关键特性是诸如转速（rpm）、横向速度（mm/s）和轴向载荷（kN）等工艺参数。通过实验采用多目标优化方法研究了输入参数对结合外部尺寸和强度的影响。随着涂层厚度减小和涂层宽度增加，结合强度提高。利用扫描电子显微镜对叠加马氏体微观结构且无碳化物颗粒沉积的细化晶粒涂层进行研究，为冶金学研究增添了价值。
