The paper explains in detail the forming conditions and corrosion process of the corrosion and, by means of electrochemical corrosion and the controlling principle in dealing with corrosion explores the cause of stress corrosion cracking, corrosion condition and anticorrosion measurements of the brake accumulator of aircraft DC-8, in order.

Friction and wear properties of carbon/carbon(C/C) composites with a smooth laminar(SL) pyrolytic carbon texture and a rough laminar(RL) pyrolytic carbon texture at different braking pressures were investigated with a home-made laboratory scale dynamometer.
