ZERO-I Coating

ZERO-I Coating - photo

Our newly developed ZERO-Ⅰ(zero-one) coating uses the advantages of S-PVD, TiAlN, and TC to achieve a high hardness, a high heat resistance, and lubricating properties. With its excellent abrasion resistance, it contributes to longer lifetimes.

Features


High hardness

In the auto industry, there is an increasing use of molds under harsh conditions that involve the processing of high-tensile strength steel or processes that increase the thickness of materials. There are problems in controlling local elastic deformations that give rise to peeling of coatings. ZERO-Ⅰ not only resolves these problems, but also achieves a high hardness of Hv3,500, which exceeds the hardness of TiCN and TiAlN.


High heat resistance

Achieves resistance at 1,000 °C, which is higher than for TiAlN. It addresses oxidation from the heat of friction during cold forging, which becomes the cause of seizing, and is also compatible with warm forging.


High adhesion/Thicker films

Most PVD films have a thickness of 2 to 3μm. With ZERO-I, we have achieved both a high adhesion and thicker films via stress relaxation technologies. Therefore, we are able to improve the abrasion resistance, and also inhibit elastic deformations from occurring.

Features


High hardness

Using our company’s know-how, we have achieved improvements in hardness up to 2,600 Hv, which exceeds that of TiN (2,300 Hv)


Thicker films

In general, a thickening of a film gives rise to peeling due to the effects of compression stress. Using our company’s previous experience as a device manufacturer and with stress relaxation technologies, we have achieved both thicker films and a high adhesion.

TiAlN Coating

TiAlN Coating - photo

This is a coating having improved abrasion resistance and heat resistance through the addition of Al into TiN. Under usage environments exceeding 700 ℃, the Al component and oxygen become bound through friction heat, which generates robust Al2O3 on the outermost surface. This contributes to further lifetime improvements.
