The utility model is characterized in that the structure adopts a process technique which is similar to a crystal structure metal plating transition layer. An entire composite plating on backing material surfaces of aluminum and aluminum alloy is orderly composed of a zinc soaking layer, a transition nickel layer, a chemical nickel layer, a transition nickel layer, an acid copper layer, a transition nickel layer, a chemical nickel layer, a high sulfur nickel layer, a bright nickel layer, a nickel sealing layer, a chromium layer, an electroplating and a chemical plating. The utility model attains aluminum and aluminum alloy planting components of the composite plating with high corrosion resistance and high impact resistance, the decorative effect of the aluminum and aluminum alloy planting components completely accords with electroplated layers, and the utility model has the advantage of high corrosion resistance, CASS can reach 220 hours. The combination strength of the plating and backing material exceeds pure plating processes, the impact resistance of the composite plating is higher than a single electroplate composite plating, and the utility model remarkably improves the quality of back acid copper, the high sulfur nickel and the bright nickel.
Description
Technical field
The utility model relates to protection and the decoration technique that a kind of metal surface anticorrosive is handled, particularly a kind of aluminium and Electroless Nickel Plating of Aluminum Alloy and composite electroplated coating structure.
Background technology
At present, handle at the Al alloy parts surface anticorrosive both at home and abroad and adopt simple plating protection and be decorated cooking technique, sophisticated simple electroless plating protection and decoration technique are also arranged, but both effects and coating performance differ greatly.Aluminium and aluminium alloy simple carry out electroless plating or individual layer is electroplated and its Technology of multi-layer plating is sophisticated, but all can not accomplish existing outstanding coating mechanical property, as resistance to impact shock, again outstanding decorative effect arranged.Therefore, both reasonable compound uses just become a new direction.But because bonding force problem between the composite deposite and composite deposite and base material and coating are owing to the different qualities of the different chemical platings that cause of technology of shaping and the stress between electrolytic coating and distribution itself influence to quality of coating, all cause electroless plating and composite electroplated layer process to can not get breaking through in the application of aluminium and Al-alloy parts always, can not form qualified composite deposite, and also always see the process for treating surface of electroless plating and composite electroplated coating in industry.The quality of chemical nickel plating and composite electroplated layer aluminium and Al-alloy parts is decided by two aspects, the one, the character of coating, the 2nd, the bonding force of coating and workpiece, adopting the whole composite deposite of traditional electroplating technology on aluminium and Al-alloy parts surface is by electroless nickel layer, copper layer, nickel dam, chromium layer, there is the lower problem of bonding strength, is easy to be torn from the bonding surface of electroless nickel layer and aluminium and Al-alloy parts.Adopt simple chemical nickel plating chrome-faced, though surface-brightening, and certain anti-corrosion capability is arranged, exist coating more crisp, the problem that impact resistance is relatively poor.
Summary of the invention
The purpose of this utility model is for behind plating electrolytic coating and the composite deposite on the bonding strength that solves bonding strength, chemical Ni-plating layer and base material between aluminium and Electroless Nickel Plating of Aluminum Alloy layer and electrolytic coating, the chemical Ni-plating layer, problems such as bonding strength between electroless nickel layer and base material and electrolytic coating, and optimization quality of coating, when not changing electrolytic coating decorative effect, color, the mechanical property that guarantees composite deposite does not change, improve the corrosion resisting property of composite deposite, a kind of aluminium and Electroless Nickel Plating of Aluminum Alloy and composite electroplated coating structure are provided.
The utility model aluminium and Electroless Nickel Plating of Aluminum Alloy and composite electroplated coating structure content Description:
The utility model aluminium and Electroless Nickel Plating of Aluminum Alloy and composite electroplated coating structure, it is characterized in that: aluminium and Electroless Nickel Plating of Aluminum Alloy have been taked the Technology of quasi-crystalline structue Metal plating transition layer mutually with composite electroplated coating structure, whole composite deposite on aluminium and aluminum alloy base material surface is by following coating order: zinc-impregnating layer, transition nickel dam, electroless nickel layer, transition nickel dam, sour copper layer, transition nickel dam, electroless nickel layer, high-sulfur nickel dam, light nickel dam, nickel seal, chromium layer, and through electroplating and electroless plating is combined into.
The utility model has solved the problem of above-mentioned existence, has obtained the aluminium and the aluminium alloy plating piece of good high anti-corrosion, high impact-resistant, decorative effect and the on all four composite deposite of electrolytic coating.It is high anti-corrosion that aluminium and aluminium alloy plating piece are had, and CASS can reach 220 hours; Coating and base material bonding strength surpass pure electroplating technology; Whole composite deposite impact resistance is than independent composite electroplated coating height; Significantly improve the quality that sour copper and high-sulfur nickel and bright nickel are crossed in the back.
