Ceramic, polymers and solid lubricants were used as reinforcements in the electroless Ni–P deposit, which is in-soluble in nature. Impingement of in-soluble particles has improved the hardness and wear resistance of the Ni–P deposit. However, the question still remains on the bonding of matrix and reinforcement particle during the wear at high load conditions. Hence, to strengthen the Ni–P deposit, a soluble reinforcement particle (CaBr 2 ) has been used in this study. A detail study on the role of bath composition (Nickel sulphate and CaBr 2 ) on the mechanical and tribology behavior of alkaline electroless Ni–P/CaBr 2 composite coatings is reported. Coatings were carried out with various weight combination of CaBr 2 particle (1 g l −1 , 2 g l −1 , and 3 g l −1 ) and source of nickel (16 g l −1 , 18 g l −1 , and 20 g l −1 ) in the bath. The optimum bath composition to achieve higher hard...

优化化学镀工艺参数以改善Ni-P / CaBr 2复合涂层对硬化EN-31钢的摩擦学行为

陶瓷，聚合物和固体润滑剂被用作自然不溶的化学镀镍-磷沉积物的增强剂。难溶颗粒的撞击改善了Ni-P沉积物的硬度和耐磨性。然而，在高负荷条件下的磨损过程中，仍然存在基体与增强颗粒之间的粘结问题。因此，为增强Ni-P沉积物，本研究中使用了可溶的增强颗粒（CaBr 2）。报道了对镀液成分（硫酸镍和CaBr 2）对碱性化学镀Ni–P / CaBr 2复合涂层的机械和摩擦学行为的作用的详细研究。用CaBr 2颗粒（1 gl -1，2 gl -1和3 gl -1）和镍源（16 gl -1，18 gl -1和20 gl -1）的各种重量组合进行涂层。在洗澡。
