Abstract
The invention relates to a metal abrasion-resistant and corrosion-resistant composite coating which comprises a priming layer, a PVD (physical vapor deposition)/PAVCD (plasma assisted vapor chemical deposition) coating is arranged on the priming layer, a corrosion-resistant layer extends into pores and is in contact with the priming layer, and another PVD/PAVCD is formed on the corrosion-resistant layer.
Description
Technical field
The invention belongs to field of metal surface treatment, refer to that especially a kind of abrasion-resistant metal decreases and erosion-resisting composite coating.
Background technology
In order to protect the member that bears friction to avoid wearing and tearing; this high wearing terrain such as automobile brake caliper particularly; existing technology particularly has under not having lubricating status in the material of relative motion generally by adopting coating way, by means of anti-wear more and more important with application corrosion-resistant coating.
Existing the whole bag of tricks improves frictional behavior targetedly, but these methods can't realize better anticorrosion effect, and does not have enough frictional behaviors such as wear-resistant degree according to the corrosion-resistant coating that prior art provides.Existing known anti-wear employing PVD (physical vapour deposition (PVD)) or PAVCD (plasma auxiliary chemical vapor deposition) apply; the method wear-resistant respond well but corrosion resistance not enough; for anticorrosion; known technology is to electroplate or chemistry or self-catalysis mode are come stopping off, but the abrasion resistance properties of this protective layer is very low.
Be again anti abrasive protected mode of anticorrosion in order to solve; prior art has proposed the mixed bedding opinion; namely after the member bottom applies corrosion-resistant coating, apply again PVD or PAVCD layer first, or on the member bottom, apply first first PVD or PAVCD layer and then coating corrosion-resistant coating.Although this composite bed mode can solve wear-resistant and anticorrosive problem in some aspects simultaneously, if the duty etch resistant layer then can't solve wear-resistant problem upper, if anti abrasion layer upper then when athletic injury occurring, corrosion that on the contrary can acceleration means.
Summary of the invention
The objective of the invention is to improve existing rub resistance and erosion-resisting composite bed system, realizing that this composite bed namely has good frictional behavior and has again good anti-corrosion property, and technique is simple.
The present invention is achieved by the following technical solutions:
A kind of abrasion-resistant metal decreases and erosion-resisting composite coating, has the bottom of being made by metal material, has the PVD/PAVCD coating on the described bottom, and have corrosion-resistant coating on this coating; Described PVD/PAVCD coating has hole, and described corrosion-resistant coating extend among the hole and with bottom and contacts; On described corrosion-resistant coating, form again the PVD/PAVCD coating.
Described corrosion-resistant coating namely has the covalent compound attribute, has again ionic compound or metallic compound attribute.
The thickness of described outermost layer PVD/PAVCD coating is the 1/3-1/2 of the PVD/PAVCD coating layer thickness of internal layer.
Described corrosion-resistant coating is to have plating, coating chemistry or self-catalysis.
The manufacture method of described wear-resistant and erosion-resisting composite coating may further comprise the steps:
1), provides the bottom of being made by metal material;
2), the PVD/PAVCD coating is coated on the described bottom;
Erosion shield that 3), will electroplate, chemistry or self-catalysis is coated on the described PVD/PAVCD coating;
4), again a PVD/PAVCD coating is coated on 3) on the coating.
The invention has the beneficial effects as follows:
When guaranteeing abrasion resistance properties, provide corrosion resistance, and corrosion resistance has improved corrosion resistance not directly in the face of frictional layer.
