Research project: Co-Ni-P Electrodeposits for Hard Chrome Replacement
Hard Chrome has been widely used in aerospace, automotive and general engineering industries. In 2003, the world wide output value of Cr plating was approximately 20 billion dollars. The prominent disadvantage is its health and environmental impacts. Conventional Cr plating solution is consisted of chromic acid in the hexavalent state, which is extremely toxic and carcinogenic. Rising environmental challenges hence need to develop and evaluate alternative coatings are rehearsed.
