The corrosion resistance of 07X16H6 precipitation hardening stainless steel in tempered state was studied using high temperature oxidation, salt-spray test and stress corrosion test.
Gas-phase oxidation treatment resulted in distrihution of some micro-pores and ditches at the carbon fiber surface and led to stress concentration therefore, the composite strength was not high.
