Abstract：Magnetron sputtered Cr-C coatings were treated at different temperatures in the air furnace.The variation of phase structures,microhardness and adhesion of coatings at different temperatures were investigated in order to evaluate the thermal stability of Cr/C coating.The results indicated that:Cr-C coatings presented high microhardness,adhesion and good thermal stability below 600℃.The dense chromium oxide and carbide formed during the coating heated,which hindered the diffusion of oxygen atoms to the inner layers and elevated the destabilizing temperature highly,as a result,a fine heat-resistance presented.The microhardness and adhesion of coatings decreased notably after the processing temperature reached 800℃.
