Nitriding treatment is a chemical heat treatment process in which nitrogen atoms penetrate the surface of the workpiece at a certain temperature and in a certain medium. The products treated with nitriding have excellent wear resistance, fatigue resistance, corrosion resistance and high temperature resistance. The general process of nitriding process :1. Pretreatment: clean, remove oil and dry the metal surface to ensure that the surface is clean and free of impurities. 2. Nitriding treatment: The metal is placed in an atmosphere containing nitrogen and treated at high temperatures to form a nitriding layer on the surface of the metal. 3. Post-treatment: Clean and cool the metal surface after nitriding to remove the residual nitride layer and prevent its oxidation. The nitriding process is of great importance for many industrial fields, such as tool manufacturing and automotive parts manufacturing.

Black oxidation treatment is a commonly used chemical surface treatment method for metal parts, including steel, stainless steel, copper and brass. The principle of this process is to immerse the metal in a heated solution containing oxidized salt, so that the metal surface forms a black oxide film to achieve the purpose of rust and corrosion resistance. This oxide film is usually iron tetraoxide (Fe304), which not only improves the corrosion resistance of the metal, but also gives it a black appearance. This surface treatment is widely used in areas such as precision machining projects, automotive parts, tools and decorations, and the advantages of black oxide include better corrosion protection, reduced light reflection, dimensional stability and aesthetic appeal. In short, the black oxidation treatment is a versatile technology suitable for the improvement and protection of various metal parts.

Plastic blasting abrasives type WIWOX® KS have been specially developed for optimum, chemically neutral surface treatment and all gentle cleaning – especially for plastic and light metal. They are mainly used for paint stripping, roughening, matting, deburring and cleaning. Plastic blasting abrasives produce consistently high quality and do not cause any damage to the work piece to be treated.
