Product Description
SX80 ceramic powder chrome coating plasma spray machine,spray chrome plating equipment
Plasma spray machine SX80 has wide application on ceramic ,metal material and alloy material ,.with high bonding force and low porosity,a lot of important parts are of imported brand products ,so the quality are very good ,here I will introduce new application for the plasma machine-----coating on Artificial bone joint , which can spray Captal 30 type powder for cover of hydroxyapatite.
ponent of SX80 plasma spray machine
(1)Power supply
Silicon controlled rectifier, maximum power input: 85KW, arcing time factor: 100%, plus or minus 15% Grid fluctuation, Maximum power output: 80KW. It can work normally under Current fluctuating range: 1~2%. The power supply provides DC current for spray gun. It is controlled by intelligent module, working 24 hours without breakdown. It is the best plasma power supply in China.
(2) Transfer box
The transfer box is the transfer center of this plasma spraying equipment. It links power supply, control cabinet, heat exchanger and spray gun together. There are high frequency ignition , waterway and gas circuit alarming devices inside this box. The transfer box is moveable, with standard 5 meter long water-cooled cable.It mixes the water and electricity and sends them to the spray gun,meanwhile it offers high frequency impulse voltage which is needed when the spray gun forms the arc,and tests spay gun’s returned water’s temperature and cooled water’s pressure.It’s easy and flexible,easy to draw,is good at forming arc ,and can reduces the moment currency’s impact when the nozzle is forming arc.
(3) SX-80 control cabinet
Control cabinet is the control center of SX-80. Its input voltage and power are single phase 220V, 1Kw. It is equipped with float flowmeter, it’s digital displaying for indicating current and voltage. It has three working modes of manual control, automatic control and economic operation. It’s equipped with alarming and breakdown display unctions. It will alarm when:
(1). Pressure of main and secondary gas is lower than 0.3Mpa, or main gas flow is under 30L/min.
(2). Water temperature is higher than 50, or water flow is under 8L/min.
The control cabinet is used for controlling and adjusting water, electricity, gas and spray powder. It monitors the whole spray system so users can directly get the working parameters of the system, that is to say, you can directly read the voltage, current and so on. When the power supply or gas supply cannot meet the system requirement, there will be automatic alarming warning,which can remind the user to make corresponding adjustment. By operating the control cabinet panel, users can adjust the current and voltage to regulate the temperature of plasma arc. They can also adjust the main and secondary gas to regulate the gas flow and gas proportion for changing the length and velocity of plasma arc.
Parameter of SX-80 control cabinet
Number | Items | Basic parameter |
1 | input power supply | AC220V,50Hz/80Hz |
2 | input power | 300W |
3 | control mode | PLC Control Replay |
4 | Main gas and gas pressure | argon,nitrogen,0.6-0.8MPa |
5 | Maximum consumption of main gas | 2m3/h |
6 | secondary gas and gas pressure | hydrogen,helium,0.25-0.4Mpa |
7 | Air and pressure | dried 0.5Mpa |
8 | Gas using mode | argon,argon hydrogen,nitrogen nitrogen+hydrogen |
9 | Dimension | 610*450*1700mm |
10 | Weight | 65KG |
(4) SX-80 powder feeder
The powder feeder is used to store spray powder and send these powder to spray gun according to technological requirements. The SX-80 system is equipped with one binocular powder feeder. The range of powder particle size is 5~200m. The two tube can feed powder at the same time, the feeding speed is 8~250g/min. Users can adjust the potentiometer on control cabinet panel to regulat the feeding speed.
(5)SX-80 spray gun
We can offer customer imitative METCO 9 MB spray gun, using argon or nitrogen as main gas, hydrogen as secondary gas. The working current of spray gun: 100-800A. The working voltage: Ar+H2: 50-75V, N2+H2: 50-80V. We provide the following spray gun accessories for our customer: spray nozzle, powder and cooling air jetting shelf, water-cooled cable, electrode tip, insulator, sealing ring, and other special tools.
(6) SX-80 heating exchanger
Heat exchanger is also called refrigerator or water chiller. We use double motors compressor to make this machine smaller and save space for our customer. The spray gun is cooled down by water, and we use heat exchanger to cool down the high temperature water coming from spray gun, and then use these cooled water to cool down the spray gun again. In this way the spray gun can keep a normal working temperature and prolong the usage life of spray nozzle.

4. By the way,do you know how to choose the thermal spray technology/process ?
a. In thermal spray technology/process,, the basic factors that determine coating quality are:
(1) The heating temperature of the spray material;
(2) The velocity of spraying material impacting on the substrate material;
(3) during heating, spraying and cooling process , the oxidation degree of the spraying materials and substrate
The maximum temperature and particle velocity obtained by different thermal spraying methods are not the same. For many materials, the oxidation of sprayed particles does not meet the requirements, so it is necessary to heat and increase particle speed quickly. The technical characteristics of various thermal spraying processes are listed in the table below:
Classification | Normal flame spray | Explosion spray | Arc spray | Plasma spray |
Particle velocity/m.s-1 | 40~100 | 600~800 | 100~250 | 150~300 |
Flame temperature/℃ | 2100~2300 | 3100 | 4500 | 10000 |
Coatingporosity/% | 10~15 | 0.5~2 | 2~15 | 5~10 |
Bonding strength/MPa | 10~30 | 70~100 | 20~40 | 30~70 |
Advantages | Simple equipment, flexible process | Low porosity, high bonding strength and low substrate temperature | Low cost and high spraying efficiency | The coating is well combined and the spraying material is wide |
disadvantages | High porosity and low bonding strength | High cost, low efficiency and large noise | spraying material is limited |
High cost |
b. Principles of choosing the spraying process
(1) principle of reliability
If the coating bonding force requirement is not very high, and the melting point of the spraying materials is less than 2,500 ℃, then we can use flame spraying with simple equipment and low cost
(2) principle of applicability
For those higher requirements of the coating performance or some dearer parts, it is better to use plasma spraying. Because the melting point of the plasma spraying material is not limited, the heat source has the non oxidation performance, the coating bonding strength is high and the porosity is low
(3) Principles of economics
Arc spraying is often used in metal spraying construction with large amount of engineering.
(4)if require metal or alloy coating with high bonding force and low porosity ,you can consider supersonic plasma spraying or supersonic flame spraying (HVOF spraying machine)
(5) For large batches of workpieces, it is better to use automatic spraying. Automatic spraying machine can be purchased in a complete set, can also be designed.
