Description
技术领域technical field
本发明涉及金属粉末技术领域，具体涉及一种钛合金粉末。The invention relates to the technical field of metal powders, in particular to a titanium alloy powder.
背景技术Background technique
人体骨骼是具有一定硬度和弹性的组织，支持人体直立行走和保护体内重要脏器。在外力或疾病作用下骨骼可以发生骨折或磨损，而需要应用植入物进行必要的修复，或直接替代骨骼的功能。目前，我国城乡交通事故发生率的不断增大引起的创伤明显增多，同时我国人口老龄化以及人们对生存质量的重视等因素将会使我国对骨科植入物的需求量迅速增长。临床上应用的骨科植入物材料主要包括不锈钢、钴铬合金和钛合金等。钛及钛合金材料由于其低弹性模量、高比强度、优异的生物相容性和耐腐蚀性等特点，被广泛应用于人工关节（髋、膝、肩、踝、肘、腕、指关节等）、骨创伤产品（髓内钉、固定板、螺钉等）、脊柱矫形内固定系统等骨科领域。Human bones are tissues with certain hardness and elasticity, which support the human body to walk upright and protect important organs in the body. Bone can be fractured or worn under the action of external force or disease, and it is necessary to apply implants for necessary repair, or directly replace the function of bone. At present, trauma caused by the increasing incidence of urban and rural traffic accidents in my country has increased significantly. At the same time, factors such as my country's aging population and people's emphasis on quality of life will make my country's demand for orthopaedic implants grow rapidly. The clinically used orthopedic implant materials mainly include stainless steel, cobalt-chromium alloy and titanium alloy. Titanium and titanium alloy materials are widely used in artificial joints (hip, knee, shoulder, ankle, elbow, wrist, finger joints) due to their low elastic modulus, high specific strength, excellent biocompatibility and corrosion resistance. etc.), bone trauma products (intramedullary nails, fixation plates, screws, etc.), spinal orthopaedic internal fixation systems and other orthopedic fields.
现有的钛合金材料通常会用钛合金粉制作，但是现有的钛合金粉的硬度、强度、耐磨性和韧性都有所欠缺，特别是在打印研磨性材料的时候，磨损度高。The existing titanium alloy materials are usually made of titanium alloy powder, but the hardness, strength, wear resistance and toughness of the existing titanium alloy powder are lacking, especially when printing abrasive materials, the degree of wear is high.
