【摘要】：采用電沉積方法在汽車傳動(dòng)部件用40Cr鋼表面制備Ni-nanoSiC復(fù)合鍍層。以復(fù)合鍍層中SiC質(zhì)量分?jǐn)?shù)和復(fù)合鍍層的硬度作為指標(biāo),通過(guò)正交實(shí)驗(yàn)優(yōu)化施鍍工藝參數(shù),得到最佳施鍍工藝參數(shù):攪拌速度為300 r/min、鍍液中SiC顆粒質(zhì)量濃度為20 g/L、溫度為50℃、陰極電流密度為14 A/dm2。結(jié)果表明:采用最佳施鍍工藝參數(shù)制備的Ni-SiC復(fù)合鍍層表面平整、組織致密,其磨損機(jī)制為輕度磨粒磨損,平均摩擦因數(shù)約為0.45,低于40Cr鋼的0.6;磨損量約為6.27 mg,相比40Cr鋼約降低25.6%。Ni-nanoSiC復(fù)合鍍層能夠提供有效的防護(hù),改善和提高40Cr鋼的抗磨損性能。
[Abstract]:Ni-nanoSiC composite coating was prepared on the surface of 40Cr steel by electrodeposition method. Taking the mass fraction of SiC in composite coating and hardness of composite coating as indexes, the optimum plating process parameters were optimized by orthogonal experiment: stirring speed was 300r / min, SiC particle mass concentration was 20 g / L, temperature was 50 鈩，
