Background technology
Along with the development of new work engine, titanium alloy reaches widespread use on compressor blade, and titanium alloy specific strength height, corrosion stability are good, but quality is softer, anti-erosion property is poor, so need anti-impact erosion protective coating that it is protected.Solid-ceramic coating such as TiN, ZrN is superhard, wear-resisting, the anti-impact erosion, and chemical stability is high and corrosion-resistant, can play good anti-impact erosion protective action to compressor blade.Quality for the anti-erosion property of solid-ceramic coatings such as TiN, ZrN, there are not at present unified test method and test unit both at home and abroad, domestic present existing test unit is free sand trial device, be used to estimate softer coatings such as inorganic and organic, be not suitable for being used for estimating ceramic coats such as TiN, ZrN.
Summary of the invention
The utility model designs at above-mentioned the deficiencies in the prior art just a kind of solid particle air-flow erosion device is provided, its objective is can be fast and effectively the anti-erosion property of ceramic coats such as TiN, ZrN is detected, and the anti-erosion property that can be used for other metal material, nonmetallic materials and other coating material detects.
The purpose of this utility model is achieved through the following technical solutions:
This kind solid particle air-flow erosion device; by the erosion unit; erosion chamber and air supply unit are formed; it is characterized in that: the erosion unit is by removable specimen mounting; spray tip; spray gun; feeding hopper is formed; the erosion chamber is the casing of a sealing; the charge door that comprises the top; the erosion particle of bottom reclaims drawer; the sliding door of side and form; air supply unit is by tracheae; reduction valve; solenoid valve; gas-holder is formed; removable specimen mounting is fixed on the indoor worktable of erosion; feeding hopper is fixed on the spray gun; spray gun is fixed on the backing plate; backing plate is installed on the worktable; removable specimen mounting is arranged on the front of the nozzle of spray gun, and spray gun connects reduction valve successively by tracheae; solenoid valve and gas-holder.Length of trachea between reduction valve and the spray gun can not be greater than 2 meters, and spray tip center and removable specimen mounting are centered close on the straight line, and the spray angle of the nozzle of spray gun is 45 °.
During test, open solenoid valve, pressure gas flows out from gas-holder, be transferred to needed erosion pressure through reduction valve, close reduction valve, open charge door, on removable specimen mounting, put the erosion sample well, adjust angle of attack and nozzle apart from the distance between the erosion sample, solid erosion particle is put into feeding hopper from charge door, close charge door, open reduction valve, the solid erosion particle that pressure gas drives in the feeding hopper goes out from nozzle ejection, is injected on the erosion sample on the removable specimen mounting, finishes erosion test one time.
Advantage that the present invention has and beneficial effect, a kind of pressurized air stream solid particle erosion device erosion unit, as a whole structure in erosion chamber of estimating the coating anti-erosion property of the present invention, by with the cooperating of air supply unit, realize erosion test.Angle of attack of the present invention is adjustable, and the erosion distance is adjustable, erosion adjustable in pressure, erosion device sealing environmental protection.Removable specimen mounting can be adjusted spray tip apart from distance and angle of attack between the erosion sample.The replacing that sliding door and charge door are convenient to place the erosion sample, are adjusted removable specimen mounting, clear up erosion chamber and spray gun.The erosion chamber is in closed state at work, prevents the injury of erosion granule dust to environment and personnel, and the form of erosion chamber and charge door can immediate observation erosion situations, and the erosion particle reclaims the recovery that drawer is used for solid erosion particle.Adjust erosion pressure and can control solid particle erosion speed.Spray tip center and removable specimen mounting 1 are centered close on the straight line, can guarantee that the erosion zone is positioned at the center of erosion sample.The present invention adopts plank and glass fabrication and processing, and is simple in structure, is convenient to operation.Can be fast and the anti-erosion property of ceramic coats such as effectively evaluating TiN, ZrN, also can be used for estimating the anti-erosion property of various metal materials, nonmetallic materials and other coating material.
