| Abstract: | The Ni-Co-P electroless deposit coating was obtained by adding CoCl2 to the Ni-P polybasic electroless deposit solution.Compared with that of the Ni-P coating,the property of the Ni-Co-P coating was improved.The effect of CoCl2 on deposit as well as the effect mechanism were studied.The micro-hardness and corrosion resistance of the coating in a hot solution were improved effectively by adding certain CoCl2.The CoCl2 could also prevent the crystallization of the coating and increase the crystallization temperature. |
