Aluminum alloy processing method, aluminum alloy and medical device resistant to high temperature and damp heat sterilization

Abstract

The invention relates to a processing method of aluminum alloy, aluminum alloy and medical equipment resistant to high temperature and damp heat sterilization. The processing method includes: S1: subjecting the aluminum alloy to low temperature treatment; The alloy is subjected to high-temperature heat treatment; S3: pre-treat the aluminum alloy after high-temperature heat treatment obtained in the previous step to obtain a smooth surface that is conducive to anodizing; S4: perform low-temperature anodizing treatment on the pre-treated aluminum alloy, and then seal Hole treatment, that is, the aluminum alloy that is resistant to high temperature and damp heat sterilization. This method can overcome the problems of lightening of the color of the aluminum alloy oxide film, local unevenness in the shape of "fog" and cracking and falling off of the point-like "powder falling" after repeated high-temperature and humid heat sterilization, and improves the tolerance of medical devices. The performance of repeated high-temperature steam sterilization can not only make medical devices play a better role in use, but also prolong the service life of medical devices.

Description

A kind of aluminum alloy processing method resistant to high temperature and moist heat sterilization, aluminum alloy and medical equipment technical field The present invention relates to metal surface treatment technical field, especially a kind of aluminum alloy processing method resistant to high temperature and moist heat sterilization. Law, aluminum alloy and medical equipment. Background technique Aluminum alloy is widely used in building decoration, household kitchen utensils, food due to its low density and high strength characteristics. Processing and surgical tools for medical devices and other fields. In order to solve the shortcomings of low surface hardness and single color of aluminum and aluminum alloys, the Porous hard anodized films are often prepared on the surface of aluminum or aluminum alloys to improve wear resistance. At present, the conventional aluminum alloy in the industry The production process of gold structural parts is basically to f...
