Description
Technical field
The present invention relates to a kind of hard coat efficiently and move back coating method, in particular a kind of hard coat is with moving back dusting, the moving back masking liquid and move back coating method of configuration.
Background technology
Along with the contradiction such as resource, energy shortage and environmental problem in recent years, the China of big country is manufactured as the world, the mechanical industry of its fast development, automotive industry, the manufacturing such as aviation and electronic industry expand further to the demand of high-performance cutter, rise of starting material, cost of labor etc.; The manufacturing philosophy of " efficient, precision, compound, environmental protection " is widely accepted, and coating technology also obtains rapid researchdevelopment thereupon, and this advanced manufacturing technology is one of developing direction becoming modern processing also.The current method preparing coating has a variety of, but is mainly divided into two large classes: chemical vapour deposition (ChemicalVapor Deposition, CVD) and physical vapor deposition (Physical Vapor Deposition, PVD) technology.
Hard coat from the earliest TiN coating, Dyadic transition group metal element carbide coating is first studied, has occurred CrN hard coat subsequently, and they all have higher chemical stability.Greatly can reduce rubbing factor, polynary, multilayer, gradient, nano combined hard coat and multi task process compound hard coat are developed, thus utilize the compound of different coating material and treatment technology, produce synergistic effect, make new advances, more high performance composite modified layer is created, to meet its final use properties requirement at workpiece surface.
Along with the development of hard coat technology, workpiece uses hard coat that its production efficiency is significantly improved, but can strengthen production cost undoubtedly, how can to greatest extent cost-saving become one of most problem demanding prompt solution at present.
Consider to reduce production cost from the work-ing life of workpiece, this will consider the life-span of hard coat, thus adopt chemical process that hard coat is decomposed after proposing the use of hard coat workpiece, and then plating hard coat, reach the object of workpiece recycling like this, save production cost, thus along with the fast development of hard coat, move back the Chaoyang being coated with industry and also will rise up slowly.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, providing a kind of hard coat with moving back dusting, the moving back masking liquid and move back coating method of configuration, realizing moving back painting fast and effectively.
The present invention is achieved by the following technical solutions, and a kind of hard coat of the present invention, with moving back dusting, comprises NaOH crystal and NaH that quality proportioning is 1:8 ~ 1:15
