We know that in the copper-nickel-chromium plating process, there are often a variety of failures, in which the poor bonding of the plated layer is a plater often encountered, then, this issue of the article we will discuss the use of alloy chemical degreasing powder, what are the things need to pay attention to, so as to ensure that the bonding of the plated layer is good.
Electroplating is a physico-chemical process that utilizes electrolysis to form a uniform, dense, and well-adhered coating on metals, alloys, or other conductive materials. During the plating process, the cleanliness of the surface of the workpiece is directly related to the quality of the plating. Especially, electroplating degreasing process is one of the key steps to ensure the quality of electroplating.
Electroless nickel plating is a common and important process, which aims to provide the surface of products with wear-resistant, corrosion-resistant and aesthetic properties. However, in practice, we often encounter the problem of discoloration of the appearance of the plated layer, especially the water stains formed during the drying process after washing, which is the main cause of the poor appearance of the plated layer. To solve this problem, Bigely plating dewatering agent BC-13 can ensure the bright and beautiful appearance of the plated layer.
In the process of using zinc-nickel alloy natural color passivator, when there is a problem with the passivation film, such as blue passivation film, is this caused by the problem of passivator? Actually, it's not. Maybe it's the plating solution.
Mr. Tu from Wenzhou, Zhejiang Province is the owner of a processing plant that processes plastic plating and multi-layer nickel plating. Recently, Mr. Tu found that the palladium activation working solution he used in the production process would produce more hydrochloric acid fog. Considering that the acid fog would pollute the environment and harm human beings, Mr. Tu wanted to find a colloidal palladium water without acid fog.
Electroless nickel plating technology is famous for its good corrosion resistance, uniform coating thickness and hardness. After the use of electroless nickel plating solution Ni-811, the hardness of the coating can reach 550-650 HK100 after plating. Then, through further heat treatment at 400℃ for one hour, the coating hardness can be further increased to 850-950 HK100. Why is Ni-811 so special? We will examine this problem in the following.
