Description
Technical field
The present invention relates to manufacture again recovery technique field, metal surface, specifically refer to a kind of surface reparation nano composite plating layer process of manufacturing again that is applied to.
Background technology
Since the industrial revolution, the mankind, in creating huge material wealth, have also paid huge resources and environment cost. Traditional a large amount of consumption with resource realize industrialization and modern Economic Development Mode has consumed earth resource terrifically. Current present situation is that the problem of shortage of resources has seriously restricted economic sustainable development. In addition, China is used big country as equipment, and existing equipment total assets reaches many trillion unit, wherein scraps because of key components and parts abrasion, excessive corrosion, fatigue failure with regard to the electromechanical equipment of valuable hundreds billion of units every year. According to statistics, 2010, there are 2,000,000 motor vehicle liquidations, 1,500 ten thousand household electrical appliances are scrapped ..., and average annual learies is be in rapid growth period. Write-off equipment melt down melting processing mode, paying under the condition of a large amount of energy costs and human cost, only can obtain the regrown material lower than product raw material quality; The concentrated stacking of write-off equipment is processed has become " social effects of pollution " greatly, has had a strong impact on the ecological environment of periphery, threatens human health. Therefore, based on the requirement of sustainable economic development, necessary Developing Circulation Economy, adhere to minimizing in recycling economy, recycling, the 4R principle of manufacturing again, recycling, give full play to the effect being manufactured on again in waste and old electronic product resource maximization, Speed-up Establishment conservation-minded society and friendly environment society.
The important method that Modern Surface Engineering Technology is repaired as the parts that lost efficacy in manufacturing engineering again, on the one hand, realize the former design size of inefficacy part and recover and the requirement of surface property; On the other hand, be different from new product surface preparation process, manufacturing surface engineering technology has its particularity again, manufacture again in reparation at electronic product key components and parts especially abrasion part, coating must possess very excellent reprocess, anti-extrusion, antifriction damages, the key performance such as corrosion-resistant. Therefore, the research and development of the Modern Surface Engineering Technology based on manufacturing are again extremely urgent, are one of important essential elements of productive forces realizing Circular Economy and " amphitypy society " construction.
Chemical plating is a Modern Surface Engineering Technology that development in recent years is got up, and its operation principle is in power-source free situation, utilizes reducing agent the reduction of metal ion to be obtained to the method for alloy layer at the surface of the work with catalytic activity. The advantages such as electroless plating technology is low, simple to operate with its less investment, cost, coating even compact, porosity is low, profiling is good are widely used in the industrial departments such as machinery, electronics, mould, metallurgy, petrochemical industry, waterpower, Aero-Space. The chemical plating industrial output value of the developed countries such as the U.S., Japan and European Union just increases progressively with annual 15% high speed. And the Application in manufacture again of repairing based on inefficacy key components and parts, current chemical plating system and technique have following weak point: 1, the re-workability of plating piece is poor, and there is the risk of bubbling, coming off in coating in reprocessing process; 2, thickness of coating does not increase, in theory, chemical plating is the process of a self-catalysis, the thickness of coating is unrestricted, but owing to having stress large (internal stress, external carbuncle) and the bad problem of adhesion between coating and parent metal, therefore in coating Thickening Process, easily cause coating performance to worsen and there is no use value; 3, Corrosion Protection, anti-wear performance etc. need further to be improved.
