Surface treatment of the stainless steel plate (SUS304) to improve the adhesion strength with epoxy resin using low-pressure argon inductively coupled plasma (ICP) has been carried out. The adhesion strength with the epoxy resin for the plasma treated stainless steel plate was compared with those of the chemical etched, sand blasted and no treated plates. Plasma treated test piece showed the highest adhesion compared with those treated by other methods and the value of adhesion strength was increased by a factor of 3 larger than that of no treated test piece regardless of the relatively small value of roughness of the treated surface. The experimental results are discussed using SEM observation and also the roughness curves. It is concluded that the surface roughness created by deposition of the plasma sputtered species on the test piece is responsible for the highest adhesion obtained.
