Testing Method for Oxide Film Thickness and Hardness of Automobile Aluminum Alloy Components
The anodic oxide film on automobile aluminum alloy parts acts like a layer of armor on their surface. It forms a dense protective layer on the aluminum alloy surface, enhancing the corrosion resistance of the parts and extending their service life. Meanwhile, the oxide film has high hardness, wh...Read more -
Selection of Test Force in Micro-Vickers Hardness Testing for Metallic Surface Coatings such as Zinc Plating and Chromium Plating
There are many types of metallic coatings. Different coatings require the different test forces in microhardness testing, and test forces cannot be used randomly. Instead, tests should be conducted in accordance with the test force values recommended by standards. Today, we will mainly introduce ...Read more -
