Problems solved by technology
[0003] Common platinum has a Vickers hardness range of 70-80 according to its platinum content. Although this hardness is greater than that of gold, silver and other metals, it is still prone to scratches and other phenomena when it is made into platinum jewelry.
The appearance of scratches greatly damages the appearance and luster of platinum jewelry, resulting in a serious decline in aesthetics and shortening the service life of jewelry

Abstract
The invention relates to the technical field of metal treatment, and discloses a carburizing agent. The carburizing agent comprises a carbon supply agent, a seeping catalysis agent, a filling agent and an adhesion agent; and the carbon supply agent is boron carbide, the seeping catalysis agent is barium carbonate, the filling agent is calcium carbonate, and the adhesion agent is dextrin, wherein the boron carbide is 40-50 parts, the barium carbonate is 5-15 parts, the calcium carbonate is 1-2 parts, and the dextrin is 1-2 parts. The carburizing agent has the beneficial effects of being high incarburizing efficiency and capable of easily controlling the carburizing degree; and the carburizing agent is utilized for performing carburizing on platinum, the surface strength of a platinum product can be effectively improved, and therefore the quality of the platinum product is improved, the service life is prolonged, and the surface of the platinum product is smooth, clean and attractive.
Description
technical field [0001] The invention relates to the technical field of metal treatment, in particular to a carburizing agent and a method for carburizing platinum using the carburizing agent. Background technique [0002] Platinum is known as the “love metal” for its characteristics of never fading and never wearing out. It is regarded as the best witness of a long-lasting marriage and naturally becomes the first choice for wedding ring materials. [0003] Common platinum has a Vickers hardness range of 70-80 according to its platinum content. Although this hardness is greater than that of gold, silver and other metals, it is still prone to scratches and other phenomena after being used as platinum jewelry. . The appearance of scratches greatly damages the appearance and luster of platinum jewelry, resulting in a serious decline in aesthetics and shortening the service life of jewelry. It is necessary to increase the hardness of platinum to avoid this phenomenon. Content...
