Abstract
The invention relates to a wear-resisting and corrosion-resisting composite coating. The coating comprises a bottom layer made of an iron material; a physical vapor deposition (PVD)/ plasma-assisted chemical vapor deposition (PAVCD) coating is formed on the bottom layer, and a corrosion-resisting layer is formed on the PVD/PAVCD coating; the PVD/PAVCD coating has pores; the corrosion-resisting layer is extended into the pores and contacts with the bottom layer; and then the PVD/PAVCD coating is formed on the corrosion-resisting layer again.
Description
Technical field
The invention belongs to field of metal surface treatment, refer to especially a kind of wear-resistant and erosion-resisting compound coating.
Background technology
In order to protect the member that bears friction to avoid wearing and tearing, existing technology particularly has under not having lubricating status in the material of relative movement 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 rubbing characteristics targetedly, but these methods can't realize better anticorrosion effect, and does not have enough rubbing characteristicss such as wear-resistant degree according to the corrosion-resistant coating that prior art provides.Existing known anti-wear employing PVD (physical vapor deposition) or PAVCD (plasma auxiliary chemical vapor deposition) apply; the method wear-resistant respond well but corrosion resistance not enough; for protection against corrosion; known technology is to electroplate or chemistry or autocatalysis mode are come stopping off, but the abrasion resistance properties of this protective layer is very low.
Be again anti abrasive protected mode of protection against corrosion 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 sport 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 rubbing characteristics and has again good anti-corrosion property, and technique is simple.
The present invention is achieved by the following technical solutions:
Wear-resistant and erosion-resisting compound coating has the bottom of being made by ferrous material, has the PVD/PAVCD coating on the described bottom, and has 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 coat-thickness of internal layer.
Described corrosion-resistant coating is to have plating, coating chemistry or autocatalysis.
The manufacture method of described wear-resistant and erosion-resisting compound coating may further comprise the steps:
1), provides the bottom of being made by ferrous material;
2), the PVD/PAVCD coating is coated on the described bottom;
Erosion shield that 3), will electroplate, chemistry or autocatalysis 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 erosion resistance not directly in the face of friction layer.
