In vacuum ion coating, high purity gases (oxygen, nitrogen, argon, acetylene) are discharged under vacuum conditions to achieve coating. That is, metal under specific conditions, and high purity gas comprehensive action to form ion. At high speed, impact machining workpiece surface. The ion firmly adheres to the surface of the workpiece to form a film layer.

In vacuum ion coating, the color of products produced by different gases will be different. Argon gas is generally used to create a coating environment. When titanium and chromium are plated, silver and yellow products can be produced by filling with nitrogen. To produce a black or gray product, acetylene gas is added. Oxygen is added to produce a blue product. In addition to gas, the color of the product produced is also affected by pressure, temperature, time and other conditions.

Application of vacuum coating

The PVD coating process for different molds (plastic molds, metal stamping molds, die-casting molds, mold parts, molding molds, etc.) and mechanical wear-resistant, corrosion-resistant parts and other high-demand hardware products can significantly improve the surface hardness, wear resistance, corrosion resistance, heat resistance and lubricability of products; And can be convenient to remove the film, greatly improve the quality of molds, parts (such as surface roughness, wear resistance, precision, etc.) and service life, so that it can effectively play the potential of products. Early failure often occurs during the use of the die. The factors of failure are usually wear, corrosion, fusion, adhesion, etc. The problem is not only to delay the production cycle, but also greatly increase the production cost, and then affect the competitiveness of enterprises. To this end, the industry has launched different solutions, and PVD coating surface treatment technology is the most popular solution, can effectively solve the above problems. PVD coating technology can be widely used in all kinds of wear, bite, corrosion, adhesion, fusion caused by failure of tools, molds, mechanical parts, medical equipment, etc. Among them, the failure caused by wear products (such as: blanking, cold heading, powder molding, etc.) coating can improve the life of more than 2-20 times; Due to the bite caused by the product or mold strain problems (such as: elongation die, stretch die, flanging die, etc.), coating can be fundamentally solved.

Main applications of vacuum coating:

1. Cutting Tools

The microstructure of PVD coating with fine nanoscale particles has the characteristics of high toughness, high hardness and high oxidation resistance, and can achieve a very smooth surface without friction during processing. In the process of coating deposition, it can achieve super adhesion between the coating and the product matrix, and at the same time, it can effectively control the deposition thickness of the coating (single side 0.5 microns -- 5 microns), for different product types of coating treatment. The tool after PVD also has the thermal stability after CVD, so as to realize the powerful and efficient processing of the tool (broach, milling cutter, wire tapping, drill, knife grain, split rod, etc.), so that it has excellent performance. www.pvd888.com

2. Mould, Mould Parts and Machine Parts

The PVD coating process for different molds (plastic molds, metal stamping molds, die-casting molds, forming molds, drawing molds, stretching molds, flanging molds, etc.) and mold parts (punching rods, thimble), mechanical wear-resistant, corrosion-resistant parts and other high-demand hardware products can significantly improve the surface hardness, wear resistance, corrosion resistance, heat resistance and lubricability of products; And can be convenient to remove the film, greatly improve the quality of molds, parts (such as surface roughness, wear resistance, precision, etc.) and service life, so that it can effectively play the potential of products.

3. Medical Equipment, Metal Hardware Products

PVD coating technology can be widely used in all kinds of wear, bite, corrosion, adhesion, fusion caused by failure of tools, molds, mechanical parts, medical equipment, etc. Among them, the failure caused by wear products (such as: blanking, cold heading, powder molding, etc.) coating can improve the life of more than 2-20 times; Due to the bite caused by the product or mold strain problems (such as: elongation die, stretch die, flanging die, etc.), coating can be fundamentally solved. Suitable materials for PVD coating treatment: metal materials that can withstand heating temperatures greater than 230 degrees without being affected.
