一、前言化学镀镍是以化学药剂做为还原剂,依靠金属表面的自动催化性质来取得镀层的。早在十八世纪中页就开始了以次磷酸盐还原金属的研究工作,但直到1944年才第一次取得紧密镀层,并在1950年得到了工业上的应用。我国是在60年代初期开始应用的,一些大型厂矿、国防工业对此做了许多研究工作。目前已广泛应用于化工、仪表、航海等要求耐腐蚀工业部门中。 First, the preface Chemical nickel plating is a chemical agent as a reducing agent, rely on the automatic catalytic surface of the metal to obtain the coating. As early as the mid-18th century, the study of the reduction of metals with hypophosphite began. However, it was not until 1944 that it was first time compactly coated and was industrially applied in 1950. Our country started to apply in the early 1960s. Many large factories and mines and defense industries have done a lot of research on this issue. Has been widely used in chemical, instrumentation, navigation and other requirements of the corrosion-resistant industrial sector.
