Abstract
Abstract The Ni-Co alloy was coated with Ni-Co-TiN/CeO 2 by Jet electrodeposition to enhance the properties of Nickel-Cobalt (Ni-Co) alloy. The morphologies, texture orientation, microhardness, coating adhesion, wear resistance, and corrosion resistance of Ni-Co-TiN/CeO 2 composite coatings were characterized. The influences of concentration of mixed particles (micron-TiN and nano- CeO 2 ) on microstructural, surface properties, mechanical properties and anti-corrosion performance of the composite coatings were studied. The addition of nano-mixed particles changed the morphology of Ni-Co-TiN/CeO 2 composite coating from large cellular protrusion structures to fine granular structures, the mechanical properties and anti-corrosion performance of Ni-Co-TiN/CeO 2 composite coatings were improved. The composite coating exhibited superior microhardness, bonding force, wear resistance and anti-corrosion performance, when the concentration of mixed particles was 4 g l −1 . This work contributed to the development of a variety of micro- and nanoparticle phase-enhanced metal-based composite coatings.
摘要:采用喷射电沉积方法在Ni-Co合金表面涂覆Ni-Co- tin /CeO 2，以提高Ni-Co合金的性能。对Ni-Co-TiN/ ceo2复合镀层的形貌、织构取向、显微硬度、镀层附着力、耐磨性和耐腐蚀性进行了表征。研究了混合颗粒(微米tin和纳米ceo2)浓度对复合镀层的显微组织、表面性能、力学性能和防腐性能的影响。纳米混合粒子的加入使Ni-Co-TiN/ ceo2复合镀层的形貌由大细胞状突起结构转变为细颗粒结构，提高了Ni-Co-TiN/ ceo2复合镀层的力学性能和防腐性能。当混合颗粒浓度为4 g l−1时，复合涂层具有优异的显微硬度、结合力、耐磨性和抗腐蚀性能。这项工作促进了各种微颗粒和纳米颗粒相增强金属基复合涂层的发展。
