| Abstract: | Effects of different spraying voltage and current, surface pretreatment, pre-heat, and subsequently heat treatment on bonding strength of arc sprayed 3Cr13 steel coating were investigated. The results indicate that the suitable voltage and current are 28 -35 V and 170 - 180 A for arc spraying 3Cr13 steel wire with diameter of 2 mm. Sand blast is the optimum method for surface pretreatment to enhance the bonding strength between coating and matrix. Applying a suitable surface pretreatment, spraying base coating and strictly controlling heat input into the base metal are the effective ways to improve the bonding strength of arc spraying 3Cr13 steel coating. |
