摘　　要：研究了镀液纤维浓度对镀层纤维含量的影响规律 ,探讨了碳纤维提高Ni P合金复合镀层的硬度和耐磨性的机理。结果表明 ,镀层碳纤维含量随镀液碳纤维浓度的增加先提高后降低 ,当镀液中碳纤维含量为 6 g/L时 ,镀层中碳纤维含量达到最高值(2 4 1% ,体积分数 )。碳纤维的加入使镀层硬度和耐磨性显著提高 ,镀态下和经 40 0℃× 1h时效处理后的镀层硬度分别为6 34HV和 1319HV ,比同一状态下Ni P镀层的硬度分别高 35 %和 6 1% ;5 0 0℃× 1h时效后的耐磨性是Ni P镀层的 6倍 ,是38CrMoAl钢氮碳共渗层的The effects of compound chemical plating technique of nickel phosphorus alloy and carbon fiber content in the solution on the hardness and wear resistance of coating are researched.The results show that the carbon fiber content in coating increases first,then decreases with the carbon fiber density in solution.When the carbon fiber density is 6g/L,the carbon fiber content in coating reach to a maximun (24.1%,vol.).The hardness of the coatings with carbon fiber in as coated and aged in 400 ℃×1h is 434HV and 1319HV respectively,35% and 61% higher than that of Ni P coating in the same state.After 500℃×1h aging,the wear resistance of coating with carbon fiber is over 6 times as that of normal nickel phosphorus alloy coating and 7 times as that of nitrocarburized case of steel 38CrMoAl.The mechanism of carbon fiber and the wear resistance are also explored.
