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 undergone heat treatment or have additives 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 that occurs during heating, which is a drawback of chromate treatment. In recent years, there has been a growing awareness of environmental measures globally, and many industries, including automotive and semiconductors, are considering alternatives to hexavalent chromium. Among these, it is being used as a substitute for chromate plating. On the other hand, compared to chromate treatment, managing the stirring state of the plating material, immersion time, temperature, and pH is more challenging, which can lead to inconsistencies in appearance and color. Furthermore, in general chromate treatment, the color may change as corrosion begins.
