Surface treatment service for magnesium alloy products

The effect of passivation Due to corrosion sensitivity, key applications have attracted the effect of passivation. Anodizing is the best practice method for magnesium passivation. Anodizing significantly enhances corrosion resistance. We provide anodizing and pre-anodizing activators for electrochemical baths.

Magnesium has recently been used in a wider range of applications including medicine. The chemicals are provided in liquid form. Depending on the current density, anodizing chemicals can provide various shades. The magnesium alloy passivator has passed ASTM and other international standards. Assess the biocompatibility of magnesium.

Surface treatment plays an important role in improving the corrosion resistance of magnesium alloys. Micro-arc oxidation technology is a promising surface treatment method, which is based on the traditional anodic oxidation process. The film can slow down the corrosion rate of magnesium alloy

However, due to strong spark discharge, the film is prone to micropores and microcracks. These porous structures make corrosive ions accelerate the corrosion of the matrix, which is not conducive to the corrosion protection of the magnesium alloy matrix. In order to improve the corrosion resistance of magnesium alloys and at the same time improve the surface properties of the coating, it is very important to study the corrosion resistance of composite coatings on magnesium alloys.

A thin E coating can be quickly deposited on the surface of Mg alloy in the cathode E coating bath without applying any current or potential. The selective self-deposition coating is due to the high surface alkalinity of Mg. The "chemical" electronic coating pre-film can provide adequate corrosion protection for magnesium alloys. After curing, the stability of the film can be further significantly improved

Magnesium alloys are also becoming viable biodegradable materials and battery electrodes. Although magnesium is currently used in the largest amount in history, the widespread use of magnesium alloys is still limited by many inherent limitations, including easy corrosion, easy formability and low creep properties. This review covers the latest research on magnesium alloy corrosion; including applying modern methods to understand magnesium corrosion, establishing an electrochemical framework for magnesium corrosion, lighting alloying effects, and trying to make corrosion-resistant magnesium alloys.
