Technology uses chemistry, the method for physics changes the chemical component or institutional framework of workpiece or material surface to improve its property
The mode of energy.It can also be avoided using surface modification mode to antifouling metal smelt, be added while meeting anti-pollution and requiring
The requirement of work technique.And change of gradient is presented with case depth in the ingredient of modified layer, i.e., between stain-proofing layer and basis material not
There are performance mutation.
Up to the present, sufacing focuses primarily upon the skills such as pack cementation, ion implanting in antifouling progress
Art.Such as king's generation is gloomy et al. seeps copper method using solid and carry out copper infiltration on 0Cr18Ni9 stainless steel, has studied and seeps copper temperature
The anti-pollution of influence and infiltration layer with soaking time to alloying layer thickness；Li Jingang et al. using paste seep copper method 18-8 type not
Copper infiltration is carried out on rust steel, equally has studied the influence and its anti-pollution for seeping copper temperature and soaking time to alloying layer thickness；
Wuhan University of Science and Technology but intelligence steel in a manner of ion implanting the surface 2Cr13 prepare seep layers of copper, through 500 DEG C × 4h heat treatment after, inhibit
Staphylococcus aureus growth significant effect；But these methods all come with some shortcomings, such as solid seeps technology painting obtained
There are inhomogeneities for composition of layer, thus can not achieve the protection of continuous and effective；And ion implantation technique coating obtained makes
There are biggish internal stress with coating for matrix, easily lead to the spalling failure of coating.Coating can be effectively improved by lacking one kind at present
With basal body binding force, and the infiltration Cu coating and preparation method thereof of continuous effective protection can be realized.
