Abstract

The invention relates to a matrix of a diamond product and a plating process thereof. The matrix is characterized in that the matrix consists of electroplated iron or iron-nickel alloy. Electroplating solution adopted by the plating process comprises ferrous sulfate and other sulphates, ferrous chloride and other chlorides, or nickel sulfate, the ferrous sulfate and the chloride. The matrix has the beneficial effects that all of the electroplated iron, the iron-nickel alloy containing 30 to 60 percent of iron and other ferroalloy have higher hardness (HRC35-50) and good bezel setting property for the diamond. Though the matrix is worse than electroplated nickel in wear-resisting property, the matrix is in favor of the exposure of the diamond product and improves the sharpness of the diamond product. Therefore, the matrix is especially suitable for manufacturing the drill pit and the sharper of the diamond. As the cheap iron replaces the expensive nickel, the manufacturing cost of the electroplated diamond product is greatly reduced.

Description

technical field [0001] The invention relates to a manufacturing process of a diamond product, in particular to a matrix of a diamond product and an electroplating process thereof. Background technique [0002] The carcass of diamond products refers to the metal used to inlay diamonds in the product and connect with the product matrix. At present, the known carcasses of diamond products are all formed by electroplating nickel or nickel alloys, and the nickel alloys are limited to nickel-cobalt, nickel-manganese and Nickel-cobalt-manganese alloy carcass. [0003] Nickel has good inlay performance on diamond, and it also has high wear resistance. It has good connection performance with the product matrix and is easy to be electroplated. Therefore, nickel has been used as the carcass of electroplated diamond products for decades. , but nickel is a relatively expensive non-ferrous metal. The price increase in the past ten years has increased the cost of electroplating nickel tir...
