Surface laser cladding method of titanium alloy material for manufacturing surgical operating instrument

Abstract

The invention discloses a surface laser cladding method of a titanium alloy material for manufacturing a surgical operating instrument, and relates to a surface treatment method of the titanium alloy material. The method comprises the steps of: (1) surface treatment; (2) drying treatment; (3) preparation of a mixed coating material; (4) coating treatment; and (5) laser cladding treatment. The treatment method effectively improves the surface strength and the hardness of the titanium alloy material, reduces the occurrence rate of such defects as cracks and holes in the cladding process, improves the use stability of the titanium alloy material, and is higher in application and popularization values.

Description

technical field [0001] The invention relates to a surface treatment method of a titanium alloy material, in particular to a surface laser cladding method of a titanium alloy material used for manufacturing surgical instruments. Background technique [0002] Titanium alloy is widely used in our daily life because of its excellent comprehensive properties, and has gradually become one of the indispensable raw materials in aerospace, medical, automotive and mechanical fields. Among them, a variety of medical devices in the medical field, such as Adson forceps, tissue forceps, needle forceps, needle forceps with scissors, quick-mouth scissors, hemostat forceps, tissue forceps, etc., can be made of titanium alloy materials, which have light weight and strength. High, non-magnetic, never rust, can be sterilized by all known technical methods, etc., but due to the characteristics of titanium alloy itself, it also has certain defects, such as slightly low wear resistance and surface...

Problems solved by technology

Among them, a variety of medical devices in the medical field, such as Adson forceps, tissue forceps, needle forceps, needle forceps with scissors, quick-mouth scissors, hemostat forceps, tissue forceps, etc., can be made of titanium alloy materials, which have light weight and strength. High, non-magnetic, never rust, can be sterilized by all known technical methods, etc., but due to the characteristics of titanium alloy itself, it also has certain defects, such as slightly low wear resistance and surface hardness, in the long-term use Problems such as deformation may occur during the process, which requires treatment of titanium alloy materials

Laser cladding treatment is one of the more advanced methods in the existing treatment methods, which can effectively enhance the surface characteristics of titanium alloys and improve their performance. There are many cracks, and it is easy to cause problems such as stress concentration and residue, which increases the safety hazards of titanium alloy materials. Therefore, it is still necessary to improve the laser cladding treatment method.
