【Abstract】 Nickel multiple plating containing 11.3%(atoms%)SiO 2 or 5.31%(atoms%)ZrO 2 particles on copper alloy base was obtained by composite electrodeposition method. Through high-temperature oxidation and thermal cycling test at 800?℃ and 900?℃, the high-temperature oxidation performance of samples prepared previouly and adhension between composite coating and copper base were studied too. The results show that after being tested for 40 hour at high temperature, the anti-oxidation ability of two composite nickel-plated films both reaches the anti-oxidation level according to HB 5258-83, and the composite coating containing SiO 2 particles has better oxidation resistance than that containing ZrO 2 particles. The adhension between the composite coating containing SiO 2 particles and the copper base is well after thermal cycling test for 55 times.更多还原
