The coating compositions of alloy chute surfacing electrode were determ ined by using orthogonal design method.At the same time,the process properties and metallurgy properties of the new electrode were investigated and the mechanical properties were tested.By tests over and over,the ideal compound of the elect rode coating was achieved.The new electrode had better process properties.It was tested that the content of alloy dements have met the design requirement on the surfacing layer.
