What is the use of cobalt-chromium-molybdenum alloy?

Inwin-style News 2021-03-19
Introduction to cobalt-chromium-molybdenum alloy
Cobalt-chromium-molybdenum alloy (CoCrMo) is a kind of cobalt-based alloy, and is also a kind of Stellite alloy, which is a kind of cobalt-based alloy that is resistant to wear and corrosion. At first, the cobalt-based alloy was a binary cobalt-chromium alloy, and then developed into a ternary composition of cobalt-chromium-tungsten, and then later developed a cobalt-chromium-molybdenum alloy. Alloying elements such as carbon, and occasionally also contain iron-containing alloys. Powder metallurgy parts.
Brief introduction of cobalt chromium molybdenum powder
Cobalt-chromium-molybdenum powder has high sphericity, smooth surface, fewer satellite balls, low oxygen content, uniform particle size distribution, good fluidity, and high bulk density and tap density. The powder can be used in various types of metal 3D printers, including Renishaw in the United Kingdom, EOS (EOSINT M series) in Germany, Concept Laser, 3D systems in the United States, laser melting equipment, and domestic research institutions and enterprises. Research and develop selected laser melting equipment, such as Huaying High-Tech, Platinum, etc.
Uses of cobalt-chromium-molybdenum powder
Cobalt-chromium-molybdenum powder is mainly used for 3D printing into alloys as biomedical materials. Cobalt and chromium are the two basic elements of cobalt-based alloys. The addition of molybdenum can obtain finer grains and have higher strength after casting or forging . Cobalt-chromium-molybdenum alloys are basically divided into two categories: CoCrMo alloy and CoNiCrMo alloy;
1. The first category is CoCrMo alloys, usually cast products. In recent years, Beijing Iron and Steel Research Institute, Beijing Rongpin Technology Co., Ltd., and Beijing Rongdian Metal Co., Ltd. have been developed to produce deformed cobalt-chromium-molybdenum alloy products. The improvement greatly improves the comprehensive mechanical properties of the material;
2. The other type is CoNiCrMo alloy, which is usually (hot) forged and precision processed. Casting CoCrMo alloy has been used in dentistry for decades and is currently used to make artificial joints. Forged CoNiCrMo alloy is used to make joints with heavy loads such as knee joints and hip joints.
Is CoCrMo alloy medical material harmful to the human body?
Cobalt-chromium-molybdenum alloy is a prosthetic metal material that can be implanted into the human body with excellent corrosion resistance and biocompatibility, and is one of the important candidate materials for high-end orthopedic implants. A few days ago, the first domestically stable total knee replacement system product with independent intellectual property rights was officially approved for marketing, breaking the foreign monopoly pattern. Among them, the prosthetic metal parts are made of cobalt-chromium-molybdenum alloy materials. Therefore, the CoCrMo alloy medical material has little harm to the human body.
