Applications/Examples of results
Steel is widely used as a material for screws due to its easy availability, strength, and toughness. Based on carbon steel, which primarily consists of iron (Fe) and carbon (C), alloy steels that have been heat-treated or contain additions such as chromium and molybdenum are used according to applications like shape, strength, and corrosion resistance. Trivalent chromate is a surface treatment that serves as an alternative to chromate plating, providing corrosion resistance equal to or greater than traditional chromate treatment without containing harmful hexavalent chromium. Additionally, it can control the decrease in corrosion resistance during heating, which is a drawback of chromate treatment. In recent years, there has been a growing global awareness of environmental measures, and many industries, including automotive and semiconductors, are considering alternatives to hexavalent chromium; among these, trivalent chromate is being used as a substitute for chromate plating. On the other hand, compared to chromate treatment, managing the process parameters such as the stirring state of the plating material, immersion time, temperature, and pH can be challenging, which may lead to inconsistencies in appearance and color finish. Furthermore, in general chromate treatments, the color may change as corrosion begins.
