About This Product

DP-DLC is a composite specification of DLC coating (a-C:H type) with dimple processing applied to the base material surface of DLC standard membrane <DLC-EX>. Low-temperature film formation means less distortion or deformation of the base material due to heat, and it has a good reputation for its smooth and hard film quality. Dimple processing using shot peening creates countless indentations on the surface of the base material, which improves the ability to retain oil films such as lubricants and mold release agents. It is effective in improving the durability of sliding parts used in oil and punches with high friction.

■Characteristics of DLC coating

DLC stands for <Diamond Like Carbon> and is a surface treatment technology that coats metal surfaces with a thin film mainly made of carbon. DLC, which is a mixture of structures such as diamond and graphite, is harder and slippery than general ceramic coatings such as titanium-based and chromium-based, and has properties such as ``wear resistance'' and ``resistance to adhesion of non-ferrous metals.'' Excellent. The discovery of DLC dates back to 1971. At that time, a ``black, hard film'' was discovered by chance during an experiment to synthesize diamond from methane gas, and it was subsequently named DLC and research has continued. Today, it is used in a wide range of industries as a coating that supports manufacturing, including cutting tools and molds, as well as automobile parts, mechanical parts, and medical parts.

■Characteristics of a-C:H type

The a-C:H type is a DLC coating with a hydrogenated amorphous carbon structure. It contains hydrogen within the membrane and is characterized by an excellent balance of hardness and toughness. With undercoat specifications, it can be applied to various base materials such as iron, carbide, and stainless steel.
