Publication number: 20220055117Abstract: A cutting implement including a metal substrate, carbide edge(s), and coating is provided. The coating is zirconium PVD (ZrCRTiNO), which provides protection against corrosion of the metal substrate. In some instances, the zirconium PVD provides protection from corrosion for at least 200 hours. A layer of carbide can be added to one or more cutting edges of the metal substrate prior to the deposition of the coating. The carbide increases the sharpness of the cutting edges and therefore increases the life or longevity of the cutting edges. Thus, a combination of zirconium PVD (ZrCRTiNO) as a coating and carbide edges on a metal substrate can increase the life of the metal substrate by providing increased hardness, sharpness, and anti-corrosive properties.Type: ApplicationFiled: December 30, 2020Publication date: February 24, 2022Applicant: ACME UNITED CORPORATIONInventors: Dheeraj Garg, Richard S.

Publication number: 20220055235Abstract: A cutting implement including a metal substrate and a coating is provided. The coating has zirconium PVD (ZrCRTiNO), which provides protection against corrosion of the metal substrate. In some instances, the zirconium PVD provides protection from corrosion for at least 200 hours. A layer of titanium nitride (TiN) can be added to the coating to increase the hardness of the metal substrate. In such an embodiment, the layer of titanium nitride (TiN) is applied before the zirconium PVD (ZrCRTiNO). Titanium nitride (TiN) coated steel is 3 to 5 times harder than uncoated steel. Thus, a combination of titanium nitride (TiN) and zirconium PVD (ZrCRTiNO) as a coating on a metal substrate can increase the life of the metal substrate by providing increased hardness and anti-corrosive properties.Type: ApplicationFiled: August 19, 2020Publication date: February 24, 2022Applicant: ACME UNITED CORPORATIONInventors: Dheeraj Garg, Richard S.
