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.
