Surface analysis of AISI 410 stainless steel cladding with AlN, Si, Co, and W powders

In this study, the surface modiication of AISI 410 stainless steel with an AlN clad layer was investigated. For the purpose of improving the uniformity and combining ability of the clad layer, speciic amounts of elemental Si, W, and Co were added. The gas tungsten arc welding method was used for the cladding procedure. The analysis was focused on the success of the cladding procedure and the modiication efect of the clad layer. To meet the demand mentioned, electron probe microanalysis was used to detect the chemical composition, and scanning electron microscopy was used to observe surface wear. Furthermore, hardness and wear tests were used to verify the mechanical properties, and temperature measurement was used to ensure the heat dissipation. The experimental results show that the surface hardness, wear resistance, and heat dissipation of cladding AISI 410 were better than naked AISI 410.
