Effect of Surface-Micropored Process on Properties of Q235 Steel

Article Preview

Abstract:

The Q235 steel sample was surface-micropored by multicomponent permeating at 923K for 2h, electroless nickel plating at 353K for 2h and sintering at 1223K for 1h. The surface morphology, microhardness distribution, mechanical property and corrosion resistance of samples were analyzed respectively by metallographic analysis, hardness test, tensile test and corrosion test. The result indicates that the surface-micropored process can enhance the surface hardness and corrosion resistance of the Q235 steel sample, while decrease its strength and plasticity at the same time.
