The joint method and characteristics of MC nylon and metal are analyzed. Considering the productivity and economics, two materials are joined with the process of turning, knurling, and induction heating. The joint strength is determined by adhesion of the melted nylon, the size of knurl, and the interference from the difference of the diameters. The adhesion strength of the melted nylon is measured. The effects of the knurl size and diameter difference are analyzed with the statistical methods. Finally the joint strength is analyzed in the environments of low, room, and high temperature. Based on this study, the nylon/metal material is expected to be widely used as the sliding machine elements with good lubrication and strength properties.
