Shaving blade with multi-layer strengthening coating and preparation method of shaving blade

Abstract

The invention discloses a shaving blade with a multi-layer strengthening coating and a preparation method of the shaving blade. A blade base with a blade edge is prepared by adopting a composite technology of magnetic filtration cathode vacuum arc deposition and MEVVA source injection, and a strengthening layer and a lubricating layer are arranged on the blade base, wherein the strengthening layeris composed of a plurality of nanometer layers with different hardness and comprises a Ti transition layer, a TiN transition layer and a Ti-doped DLC layer which are sequentially arranged from insideto outside, and the lubricating layer is a polytetrafluoroethylene layer. Multiple transition layers such as the Ti transition layer and the TiN transition layer are introduced between the blade basematerial and the DLC film layer, meanwhile, Ti ions are injected into MEVVA source ions, the surface hardness of a shaver can be enhanced, the interface lattice effect can be optimized, the internalstress of the coating can be effectively relieved, the bonding force between the coating and the base is effectively improved, the workpiece hardness and wear resistance are improved, and the frictioncoefficient is reduced so that the service life of the workpiece can be 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] Special steel for razor blades is steel for razor blades used to shave off beard and body hair. Razor blades need to be sharp, not easy to rust, and not easy to lose flesh, that is, razor blades are the same as other knives , should have a sharp shape and durability. In order to make the razor blade have a sharp shape, it is very important to have a good sharpening process and a small amount of heat treatment deformation. In order to maintain the sharp shape of the blade for a long time, that is, durability, it is enough The properties of hardness, defect resistance (flesh loss) and good corrosion resistance are very important. [0003] Coating treatment can increase the hardness, wear resistance and reduce the friction coefficient of the workpiece, thereby prolonging the life of the w...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a razor blade with a multi-layer reinforced coating and a preparation method thereof, which effectively solves the technical problems in the prior art that the bonding force between the DLC coating and the razor blade substrate is not strong, and the coating is easily caused to fall off. In order to achieve the technical effect of increasing the hardness, anti-wear force and reducing the friction coefficient of the workpiece, thereby prolonging the life of the workpiece
