Abstract
The present invention relates to method at the matrix steel copper-depositing on surface.Be characterized in earlier copper base coating evenly being coated in the matrix steel surface of cleaning, to form certain thickness dope layer, adopt the bombardment with laser beams dope layer to obtain then, fine and close, evenly and with matrix the metal deposition film of good metallurgical binding state is arranged, technological process is simple, and is energy-conservation, efficiently reach non-environmental-pollution.
Description
The present invention relates to method at the matrix steel copper-depositing on surface.
Anticorrosion and the modification of metal material surface is the important engineering in Surface Engineering field, and anticorrosion and method of modifying commonly used has: surface treatment (oxidation, phosphatization etc.), ooze on the surface, coated layer etc.Although above technology is just extensively adopted by production department, they exist the production cycle long, shortcomings such as complex process, difficult quality control.Method and above traditional technology that the present invention proposes are all inequality, the selection of deposition region and settled layer and matrix combine two aspect be better than traditional technology, it is a new technology of being intersected by physics and material subject and forming, be new use of energetic particle beam in the material subject field, be to come the irradiation metallic-coated surface, obtain the novel method of metal deposition layer with laser.
The objective of the invention is to overcome the shortcoming that above traditional technology exists, energetic particle beam is applied to the material subject field, use the laser beam irradiation metallic-coated surface, to obtain the novel method of metal deposition layer, make its selection of deposition region and settled layer and matrix combine two aspect all be better than traditional technology.
Above-mentioned purpose of the present invention can be achieved through the following technical solutions: method of copper-depositing on surface of steel, be earlier copper base coating evenly to be coated in the matrix steel surface of cleaning, to form the 0.5-1.5mm dope layer, adopt bombardment with laser beams dope layer surface to obtain the metal deposition film then.
Said copper base coating is by SiO
2, CuO, Re
2O
3Form SiO with resol and spirituous solution
2, CuO, Re
2O
3With resol be solid additive, its ratio is 1-1.5: 2-2.5: 0.5-1: 2-2.5, the ratio of these solid additives and spirituous solution is: the weight range in the 100ml spirituous solution is a 91.67-125 gram.
The advantage of this programme is under laser beam and coated surface interaction, can inject high calorie at short notice to coat, the chemical reaction that reaches between coating and the matrix in the coating is realized in short-term, can make that chemical reaction finishes rapidly thoroughly, also help the metal refining atom to the certain slight distance of matrix internal divergence, thereby make settled layer and metallic surface that good metallurgical binding state be arranged.
Describe such scheme and embodiment in detail below in conjunction with accompanying drawing.(1) is the laser beam from laser apparatus in the accompanying drawing, and (2) are speculum, and its input angle receives the excimer bundle, and by the laser beam directive coated surface that its reflection angle reflects, (3) are coated surface, and (4) are nozzle, (5) body material for being deposited.Provided by the invention at the matrix steel method of copper-depositing on surface, can be undertaken by cleaning, coating and three steps of irradiation, at first the deposition surface of metal is cleaned with about 5% the MaHO aqueous solution.Water temperature gets final product for about 50 ℃.Then by selecting suitable a kind of formulation for coating material to be coated on the metallic surface of cleaning in the said ratio scope, use laser beam (1) coated surface (3) to be carried out radiation then through speculum (2) refraction, laser output power, bundle class diameter, degree of excursion degree belong to thickness on metal refining kind, prescription and deposition and decide.In radiative process by near the nozzle that is provided with the coat (4) to laser radiation place blow shielding gas (as nitrogen, argon gas etc.) by this scheme as long as just can on the metallic surface, obtain the metal deposition film in tens seconds.
Below with 20
#Copper-depositing on surface of steel is example explanation present method specific implementation process.Press earlier table one and prepare coating, then coating be coated in cleaned 20
#On the steel surface, then by shown in the accompanying drawing: given off laser beam (1) by laser apparatus, reflex on the coated surface (3) through refractor (2) and carry out radiation, laser output power can be 500W, and laser beam class is Φ=30mm, and power density is 0.5-1.5 watt/mm
2, just can be in tens seconds 20
#It is the Cu settled layer of 3-5 μ m that the surface forms thickness, and settled layer and matrix are the metallurgical binding state.
