Abstract

The invention discloses a razor blade with a soft and hard alternate carbon nano composite coating. The razor blade comprises a razor blade body and a metal coating arranged on the razor blade body, soft-layer carbon films and hard-layer carbon films are alternately arranged on the metal coating, and a polytetrafluoroethylene lubricating layer is arranged on the outermost layer of the razor blade body. The method has the beneficial effects that internal stress accumulation of the film can be effectively prevented, defects in the film are prevented from being diffused, cracks, warping or falling off of the coating are prevented, the surface hardness and the wear resistance of the razor blade are effectively improved, and the service life of the razor is prolonged.

Description

technical field [0001] The invention relates to a razor blade, in particular to a razor blade with multi-layer reinforced coating and its preparation technology. Background technique [0002] Among many cutting tools, the razor is a necessity in people's daily life and has the function of cutting hair on the skin. The base material of the razor blade is made of stainless steel, and the blade is required to be sharp, not easy to rust, and not easy to lose flesh. However, the razor is prone to rust and damage to the blade during use, which affects the service life of the blade. and shaving comfort. The production process of razor blades is to stamp and form 6Cr stainless steel sheets, go through a series of heat treatments (including: open flame degreasing, high temperature quenching, low temperature cold plate contact quenching, low temperature tempering, etc.), and then go through printing, sharpening, inspection, coating , then spray polytetrafluoroethylene, grill and sha...
