Abstract
The invention provides a coated piece which comprises an aluminum or aluminum alloy substrate, an amorphous alloy layer and a colored layer with an anti-corrosion function, wherein the amorphous alloy layer and the colored layer are formed on the aluminum or aluminum alloy substrate in turn; the amorphous alloy layer is Fe70Cr10B13X7; and X is any one selected from phosphorus, carbon and silicon. The coated piece has excellent corrosion resistance and decorative appearance. The invention also provides a manufacturing method for the coated piece.
Description
Technical field
The present invention relates to a kind of covering member and manufacture method thereof.
Background technology
Vacuum coating technology (PVD) is a very film technique for environmental protection.The formed rete of mode with vacuum plating has high rigidity, high-wearing feature, good chemical stability, the firm and beautiful advantages such as metal appearance of being combined with matrix, so vacuum plating is more and more wider in the application of the ornamental process field of metallic substrate surface such as aluminium, aluminium alloy, magnesium, magnesium alloy and stainless steel.
Yet, because the standard potential of aluminum or aluminum alloy is very low, and itself inevitably can there is small hole in PVD decorative coating, therefore, directly in aluminum or aluminum alloy matrix surface plating such as TiN layer, TiNO layer, TiCN layer, CrN layer, CrNO layer, CrCN layer or other, there is the PVD decorative coating of corrosion proof function, can not effectively prevent described aluminum or aluminum alloy matrix generation galvanic corrosion, simultaneously this PVD decorative coating itself also can occur heterochromatic, the phenomenon such as come off.
Summary of the invention
Given this, provide a kind of have good erosion resistance and the covering member of decorative appearance.
A kind of manufacture method of above-mentioned covering member is also provided in addition.
A covering member, comprises aluminum or aluminum alloy matrix, is formed at the amorphous alloy layer on this aluminum or aluminum alloy matrix and has the color layers of corrosion proof function successively, and this amorphous alloy layer is Fe

Described amorphous alloy layer 13 and color layers 15 all can be passed through magnetron sputtering method formation of deposits.
The method of the described covering member 10 of manufacture of a preferred embodiment of the present invention mainly comprises the steps:
Aluminum or aluminum alloy matrix 11 is provided, and aluminum or aluminum alloy matrix 11 is ground and electropolishing successively.After electropolishing, then with deionized water and dehydrated alcohol, wiping is carried out in these aluminum or aluminum alloy matrix 11 surfaces successively.Again the aluminum or aluminum alloy matrix 11 after wiping is put into the ultrasonic cleaner that is loaded with acetone soln and shaken cleaning, to remove the impurity on aluminum or aluminum alloy matrix 11 surfaces and greasy dirt etc.After cleaning, dry up standby.
Argon plasma cleaning is carried out on surface to the aluminum or aluminum alloy matrix 11 after above-mentioned processing, further removes the greasy dirt on aluminum or aluminum alloy matrix 11 surfaces, to improve the bonding force of aluminum or aluminum alloy matrix 11 surfaces and follow-up coating.Concrete operations and the processing parameter of this plasma clean can be: adopt a medium frequency magnetron sputtering coating equipment (not shown), aluminum or aluminum alloy matrix 11 is put on the work rest of coating chamber of this coating equipment, to this coating chamber vacuumize process to vacuum tightness be 1.0 * 10
-3pa, the flow of 250～500sccm (standard state ml/min) of take passes into the argon gas that purity is 99.999% in coating chamber, on aluminum or aluminum alloy matrix 11, apply the bias voltage of-300～-800V, plasma clean is carried out in aluminum or aluminum alloy matrix 11 surfaces, and scavenging period is 3～10min.
Aluminum or aluminum alloy matrix 11 is being carried out after plasma clean, on this aluminum or aluminum alloy matrix 11, forming amorphous alloy layer 13.The concrete operations and the processing parameter that form this amorphous alloy layer 13 are as follows: take argon gas as working gas, adjusting argon flow amount is 150～300sccm, to passing into flow in coating chamber, be the reactant gases oxygen that the purity of 50～200sccm is 99.999% again, it is 30%～70% that dutycycle is set, the revolution speed that described work rest is set is 0.5～3.0r/min (revoluti on per minute, rev/min), on aluminum or aluminum alloy matrix 11, apply the bias voltage of-50～-300V, and heating film-coated chamber to 100～150 ℃ (being that sputter temperature is 100～150); Select Fe
