Abstract
The invention discloses a kind of stamping parts surface coverings, it from the inside to the outside successively include transition zone, the first wearing layer and the second wearing layer, the transition zone is TiN or CrN, first wearing layer is the nanometer multilayer that TiN, CrN and MoN are alternately constituted, and second wearing layer is the mixed layer of polytetrafluoroethylene (PTFE) and molybdenum disulfide.The mixture of polytetrafluoroethylene (PTFE) and molybdenum disulfide is added in coating of the present invention, coating performance is stablized, will not react with medium, while wear-resistant coating is not influenced by environmental factor, thus can effectively resist surrounding medium effect and various chemical attacks.Wearability of the present invention is high, corrosion-resistant, long service life.
Description
Technical field
The present invention relates to a kind of stamping parts surface coverings, belong to stamping parts technical field.
Background technique
In existing production, since the hardness of stamping parts material is not high enough, wearability is not also high, in stamping parts use process
Often be bruised, weigh wounded, serious wear, spoilage is higher, and service life is short, although can by improve stamping parts material come
Reduce surface damage, but effect is undesirable, is not able to satisfy the demand of actual production.
Summary of the invention
The technical problem to be solved by the present invention is to overcome the deficiencies of existing technologies, provide a kind of wearability it is high, it is corrosion-resistant,
Stamping parts surface covering with long service life.
In order to solve the above technical problems, the present invention provides a kind of stamping parts surface covering, characterized in that from the inside to the outside successively
Including transition zone, the first wearing layer and the second wearing layer, the transition zone is TiN or CrN, first wearing layer be TiN,
The nanometer multilayer that CrN and MoN is alternately constituted, second wearing layer are the mixed layer of polytetrafluoroethylene (PTFE) and molybdenum disulfide.
Preferably, the mass ratio of polytetrafluoroethylene (PTFE) and molybdenum disulfide is 2:1 in second wearing layer.
Preferably, the outside of second wearing layer is additionally provided with lubricant layer, and the lubricant layer is MoN.
Preferably, the transition zone with a thickness of 1~2 micron.
Preferably, first wearing layer with a thickness of 2~3 microns.
Preferably, second wearing layer with a thickness of 2~3 microns.
Preferably, the lubricant layer with a thickness of 200~500 nanometers.
Advantageous effects of the invention: being added to the mixing of polytetrafluoroethylene (PTFE) and molybdenum disulfide in coating of the present invention
Object, coating performance are stablized, will not react with medium, while wear-resistant coating is not influenced by environmental factor, thus can be effective
Resist surrounding medium effect and various chemical attacks.Wearability of the present invention is high, corrosion-resistant, long service life.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following embodiment is only used for clearly illustrating the present invention
Technical solution, and not intended to limit the protection scope of the present invention.
It from the inside to the outside successively include transition zone 1, the first wearing layer 2 and the as shown in Figure 1, a kind of stamping parts surface covering
Two wearing layers 3.The transition zone 1 be TiN or CrN, the transition zone 1 with a thickness of 1 micron.
First wearing layer 2 is the nanometer multilayer that TiN, CrN and MoN are alternately constituted, the thickness of first wearing layer 2
It is 2 microns.
Second wearing layer 3 is the mixed layer of polytetrafluoroethylene (PTFE) and molybdenum disulfide, polytetrafluoro in second wearing layer 3
The mass ratio of ethylene and molybdenum disulfide be 2:1, second wearing layer 3 with a thickness of 2 microns.
The outside of second wearing layer 3 is additionally provided with lubricant layer 4, and the lubricant layer 4 is MoN, the thickness of the lubricant layer 4
It is 500 nanometers.
The mixture of polytetrafluoroethylene (PTFE) and molybdenum disulfide is added in coating of the present invention, coating performance is stablized, and will not and be situated between
Matter reacts, while wear-resistant coating is not influenced by environmental factor, thus can effectively resist surrounding medium effect and variousization
Learn corrosion.Wearability of the present invention is high, corrosion-resistant, long service life.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, several improvement and deformations can also be made, these improvement and deformations
Also it should be regarded as protection scope of the present invention.
