The chemical corrosive wear behaviours of steel G105 and electroless Ni-P alloy in air and nitrogen were studied in the condiction of unlubracation wear in this paper. The results show that the wear rates of the two materials increase and the friction coefficients decrease with increasing of normal load and sliding speed. Oxygen in the gas has obvious influence to the behaviours of steel G105. At the condition of unlubratation wear, it is not suitable that eletroless Ni-P alloy acts as a protective coating on steel G105.
