According to the present invention, above-mentioned processing method can further comprise third step, wherein, above-mentioned first powder is mixed with compressed air, blows to the metal target surface then under predetermined pressure, so that form tiny concavo-convex.The above-mentioned tiny concavo-convex 1-5 μ that is preferably dimensioned to be.
The accompanying drawing summary:
Shown in Figure 1 is that (amplify: schematic diagram * 5,000), it shows the surface appearance of metal material unprocessed after machined to SEM (SEM) photo.
(amplify: schematic diagram * 5,000), it shows the surface appearance behind first and second treatment steps to the SEM photo of the metal material surface that shown in Figure 2 is handles through the present invention's metal surface treating method.
(amplify: schematic diagram * 5,000), it shows the surface appearance behind first, second and the 3rd treatment step to the SEM photo of the metal material surface that shown in Figure 3 is handles through the present invention's metal surface treating method.
Below with reference to accompanying drawing the preferred embodiments of the invention are described in detail.With particle diameter is that 10-50 μ and the powder with nonferromagnetic substance such as aluminium oxide and carborundum (hereinafter referred to as " powders A ") mix with compressed air, then at 0.3-3kgf/cm
2Pressure under blow to the target metal materials surface.Thus, can remove unstable burr and the white layer on the metal surface and segregate to lip-deep material, and eliminate the foreign matter that is very easy to come off.
The spherical powder such as glass marble, iron ball, quartz ball or the marble ball (hereinafter referred to as " powder B ") that with particle diameter are 10-50 μ then mix with compressed air, then at 1.0-3kgf/cm
2Pressure under blow to above-mentioned metal surface.Acute angle on the metal surface is become circle and leveling, and add flat aperture, so just prevented stress the concentrating in coated ceramic that can cause priming paint to peel off.For the coating that forms by chemical vapour deposition (CVD), promptly coated film is diffused in the metal surface, and above-mentioned processing also is enough.
But, for physical vapour deposition (PVD), be crystal deposition and spread on the metal surface, and the surface of after carrying out surface treatment with powders A, handling with powder B again (be called " surface " B later on ") then be inappropriate, this is because it does not have nucleus when crystallization initiation.
Therefore, for obtaining the close crystal coating of matter, just must be wittingly concavo-convex at the last shape 1-5 of surfaces A/B μ, this concavo-convex stress that can not cause after applying is concentrated.This type of surface appearance (hereinafter referred to as " surfaces A/B/A ") can obtain by the following method: powders A is mixed with compressed air, then at 0.2-1.5kgf/cm
