There are many ways to surface treatment of Screw Wire, the following are the common ones:
Heat treatment: Change the surface structure of Screw Wire by heating to improve its hardness and wear resistance. Heat treatment usually includes processes such as quenching, tempering and surface oxidation.
Electroplating: Covering the surface of Screw Wire with a layer of metal to improve its corrosion resistance and conductivity. Commonly used electroplating materials include zinc, copper, nickel, etc.
Spray coating: Apply a layer of paint or plastic to the surface of the Screw Wire to change its appearance color and provide an extra layer of protection. Spraying materials can be selected according to specific needs, such as anti-rust paint, insulating paint, etc.
Oxidation treatment: Form an oxide film on the surface of Screw Wire through chemical or electrochemical methods to improve its corrosion resistance and aesthetics. Common oxidation treatments include blackening and anodizing.
Galvanizing: Covering the surface of Screw Wire with a layer of zinc to improve its corrosion resistance and aesthetics. Galvanizing methods include hot-dip galvanizing and electro-galvanizing.
Mechanical strengthening: Change the surface structure of Screw Wire through mechanical processing or rolling to improve its hardness and wear resistance. Mechanical strengthening includes processes such as grinding, rolling and rolling.
Chemical treatment: Change the surface properties of Screw Wire by soaking or coating with chemical solution. For example, phosphating treatment can improve the corrosion resistance and adhesion of Screw Wire.
Surface alloying: Forming an alloy layer on the surface of Screw Wire through physical or chemical methods to improve its hardness, wear resistance and corrosion resistance. Surface alloying methods include carburizing, nitriding, carbonitriding and other processes.
Each of these surface treatment methods has its own characteristics, and the selection of the appropriate surface treatment method should be determined based on specific application requirements and material properties. For example, for occasions that require high wear resistance, you can choose methods such as quenching or mechanical strengthening; for applications that require high corrosion resistance, you can choose methods such as electroplating, galvanizing, or oxidation treatment.
