Description
[technical field]
The present invention relates to plasma spraying technology fields, spray plated film rifle more particularly, to a kind of low-temperature plasma.
[background technique]
Plasma spraying technology is using the non-diverting plasma-arc of rigidity as heat source, by powder such as ceramics, alloy, metals
Powder material heating melting or semi-molten state, and high speed sprays to the surface for by pretreated workpiece surface and forming adhesion-tight
The method of layer.Wherein, the ionization that is working gas in the electric arc that anode and cathode are formed of conventional plasma spraying method be etc. from
Daughter, the powder melts or semi-molten for conveying powder mouth form coating as plasma jet is ejected into matrix surface.
Therefore, Plasma Spraying Process Using needs reasonable arc power and powder sending quantity, plasma gas, spray distance, angle
The parameters such as degree and workpiece relative velocity are vital for the raising of coating quality.Electrical power and powder sending quantity, electrical power are
The most important technological parameter of plasma spraying needs often to adjust variation in spraying process, and otherwise power is excessively high, makes spraying temperature
Height is spent, powder direct gasification causes to sputter in coating containing stomata and powder, influences surface quality, hardness reduction, gap occur
It is excessive, or even cracking and scaling loss spray gun；When power is too low, flame temperature is inadequate, and powder melts insufficient, drop adhesive force
Too low, anchoring strength of coating reduces, and spray efficiency reduces.It must mutually be fitted with factors variations such as spraying powder type, powder sending quantities
Answer, powder supply excessively melt it is insufficient, otherwise powder supply melt less and seriously will affect coating quality and matrix overheating deforming and damage etc..Spray
Applying distance influences melting degree, flight time, speed and the temperature of powder, very big on coating influence, when apart from excessive, powder
The flight time at end will increase, and reduce spray efficiency, and powder speed and temperature is caused to reduce, pressure mistake when droplets pack
Small, mobility reduces, and coating binding force and consistency is caused to reduce；Conversely, the flight time is short, speed is fast, heating is caused not filled
Point, it is big to the impact force of matrix, keep bond strength low, and may damage to matrix.The selection of spray distance should be
Under the premise of not influencing coating quality and matrix, reduce as far as possible, working efficiency is provided.The deposition efficiency of angle influence powder
And coating structure, general closer to vertical spraying, spraying effect is better, if spray angle is less than normal, coating structure deteriorates, and occurs
Hole causes porosity excessive, and coating hardness and bond strength are relatively low.
So the principle of comprehensive plasma, technique, controlling element determine existing conventional plasma there are the problem of and lack
It falls into:
1, conventional plasma spraying temperature is too high, and thousands of degree Celsius are between tens of thousands of degree.
2, conventional plasma spraying equipment application performance is single, is substantially at Single Medium spraying.
3, there is particular requirement to spraying substrate selection, need high temperature resistant substance as substrate.
4, plasma spraying equipment structure is excessively complicated, and the plasma state stability of generation is poor, poor universality.
5, production application not smart enoughization；Technical difficulty of operation is big；It is high to degree of being skilled in technique requirement.
6, air plasma spraying: being sprayed under atmospheric environment, and workpiece needs to preheat about reduction matrix to be come with coating temperature
Improve bond strength etc..
7, traditional equipment safety is low.
