Cobalt-chromium alloy powder forming method based on selective laser melting

Abstract

The invention discloses a cobalt-chromium alloy powder forming method based on selective laser melting. The method comprises following steps: using optimized contrast method to obtain the optimal process parameters for cobalt-chromium alloy powder molding; then, establishing 3D models of part structures that need to be prepared; then, using the obtained optimal process parameters as 3D printing parameters, performing layering and scanned path planning processing on the established 3D model to generate print files required for 3D printing; then importing the generated print files into a 3D printing device, and the cobalt-chromium powder is used as the molding material for 3D printing. The invention is based on the selective laser melting technology, and can accurately manufacture metal parts of various complicated structures according to actual requirements. The optimal process parameters of cobalt-chromium powder molding are obtained by optimized contrast method, and different optimalprocess parameters can be set according to the actual mechanical properties required, with high flexibility and good dynamic performance.

Description

technical field [0001] The invention relates to a metal powder molding method, in particular to a metal powder additive manufacturing molding method, and also to a laser melting material molding method, which is applied in the technical field of mechanical manufacturing and processing. Background technique [0002] Cobalt-chromium alloys are widely used in the fields of clinical medicine, dentistry, dentures and implants due to their excellent tissue mechanical properties and biocompatibility. The traditional cobalt-chromium alloy processing technology generally has problems such as complex process, many influencing factors, long processing cycle, serious waste of materials, and difficulty in precise processing of fine and complex structures. [0003] The selective laser melting technology has flexible manufacturing characteristics that other processing methods do not have, and can better overcome the above problems. At present, the processing parameters of the powder formi...
