Description
Technical Field
The invention relates to the technical field of cold spraying, in particular to a high-pressure low-temperature cold spraying brass coating device.
Background
A high-pressure low-temperature cold spray brass coating device is a material surface coating device based on ultrasonic speed cold spray, coating powder is not impacted to a substrate by supersonic gas and solid two-phase airflow at normal temperature or lower temperature to form a dense coating, the cold spray technology does not have the effect of heating the coating material powder particles at high temperature, namely the effect of influencing the coating performance such as high-temperature oxidation, gasification, melting, crystallization and the like, and can generate an anti-corrosion, anti-friction, reinforced, insulating, conductive and magnetic coating on the surface of a metal, glass and ceramic workpiece, thereby being a novel spray process which creates a new field of spray process.
The cold spraying coating device comprises a high-pressure gas source (an air compressor), a gas regulating system, a gas heater, a high-pressure powder feeder and a spray gun, wherein the high-pressure gas source generates high-pressure gas to push the airflow speed, the gas regulating control system is used for regulating the air pressure and the temperature, the heater enables the airflow to be preheated to a certain temperature, the powder feeder is a device for feeding powder into the spray gun under the state of pressure, the powder-carrying airflow sent out by the powder feeder at a mixing chamber of the spray gun is mixed with main airflow and then enters the spray pipe through a guide pipe, the carrier gas is a high-speed medium and is preheated to 0-700 ℃ in the heater before entering the spray pipe, the working gas expands to the normal pressure from the pressure of 1.5-3.5 MPa at the inlet of the spray pipe to form supersonic airflow, and the particle speed fluctuates to 500-1000 m/s along with the difference of factors such as the nozzle form, the type of the working gas, the inlet pressure and the temperature, the particle size and the density, and then accomplish the cold spraying treatment of work piece surface, simultaneously, because the inside moisture that contains of compressed air that current compressor produced, when directly getting into gas heater and heating, and the gas that real-time moisture content is difficult to control is influenced by the moisture after heating, makes its gas heating temperature often not up to standard in the in-process of rapid heating circulation, and the carrier gas temperature just directly influences the coating quality of cold spraying, therefore, in the in-service use in-process, its coating device often can install the deareator additional, guarantees that high-pressure air's drying and follow-up stable efficient heating spraying use.
However, we find in the actual use process that the coating apparatus in the prior art is installed by a plurality of bolts based on a flange plate when a gas-water separator is installed, but because the flow rate of high-pressure gas is very high in the whole cold spraying process, the gas-water separator cannot necessarily remove water by adopting an adsorption mode, the water removal efficiency is extremely low when the gas flow rate is too high, and no matter the gas separator adopts a louver type or cyclone type, because the gas separator is captured by the inertial collision of water droplets, and further, in the continuous use process, the gas flowing at high speed causes the water droplets carried by the gas separator to also have extremely high initial collision speed, so that the water droplets collide violently when captured, the local position in the gas separator is easy to fail and damage, the stable gas-water separation use is influenced, and therefore, in the continuous use process, the coating device needs to be stopped for a plurality of times in a very short period to disassemble, assemble and replace the gas-water separator, but the installation mode of a plurality of bolts which are independent causes that the disassembly and assembly work of the gas-water separator of the coating device is very troublesome every time, a plurality of fixing bolts need to be disassembled and assembled respectively repeatedly, the disassembly and assembly time of single shutdown is prolonged, and the spraying efficiency is seriously influenced, meanwhile, when the gas-water separator is damaged, disassembled and replaced every time, the conduction pipe of an air compressor and a gas heater, which is used for being communicated with the gas-water separator, can be directly exposed in the air, the replacement speed of the gas-water separator directly influences the exposure time of the conduction pipe in the air, and the gas-water separator which is seriously consumed by disassembly, assembly, replacement and replacement can cause impurity particles in the air to continuously enter the exposed conduction pipe, and further cause that the mixed particle impurities are sprayed on the surface of a workpiece during subsequent spraying, the quality of the brass cold spraying coating is seriously influenced, and therefore, a high-pressure low-temperature cold spraying brass coating device is provided.
