Guangzhou Sanxin Metal S&T COM.,LTD(in CHINA),our factory is specialized in spraying construction,coating services,and spraying equipment for more than 30 years ,a lot of important parts of the HVOF machine are of the imported famous brand ,all our products are of good quality and competitive price. we have dozens of spraying equipment ,such as thermal spraying equipment,arc spraying equipment ,plasma spraying equipment ,and so on.
SX-8000 is the typical oil HVOF spray equipment ,which is of great advantage ,while SX-5000 is gas HVOF spray equipment; with the efort of our technologists, we develop a portable HVOF spraying equipment SX2000,which is only 28kg ,can be carried to everywhere for small construction spraying ,all these three kinds of HVOF coating machine can spray Ni-Cr chrome carbide materials on the workpieces
.1.composition of hot sale HVOF spraying coating equipment ,nickel chrome powder coating, tungsten carbide powder HVOF spray machine
(1) for SX8000 and SX5000,they are both consist of control cabinet,powder feerder,cool water machine ,and spray gun

while for SX2000, it is consist of control cabinet ,powder feeder,and spray gun
,
2.Characteristics of hot sale HVOF spraying coating equipment ,nickel chrome powder coating, tungsten carbide powder HVOF spray machine
(1)NiCr18Al content: NiCr18Al hardness of coating: 20 HRC Particle size: -140M+325M;-325M
(2).The alloy prevents hot gas corrosion ,micro shake wearing.It is a good bonding material in high temperature metal coating and high temperature ceramic coating.It also can be used as high temperature oxidation resistant coating.
3.application and advantage of hot sale HVOF spraying coating equipment ,nickel chrome powder coating, tungsten carbide powder HVOF spray machine
HVOF spraying machine is widely used in spraying Tungsten carbide ,NiCr chrome carbide and Nickel chrome aluminum on the workpieces ,to improve the abrasion resistant ,wear resistant and corrosion resistant of the surface of the workpieces .




4. some knowledges of choosing the thermal spray machine
(1)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 |
|
disadvantages
|
High porosity and low bonding strength |
High cost, low efficiency and large noise |
spraying materialis limited |
High cost
|
When choosing the process method, we should also consider the mechanical properties of the spraying layer, consider the mechanical processing according to the size and shape of the parts, then decide which kind of spraying method to be used , and what is the processing cost and so on .
(2) 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.
(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 plasma spraying or HVOF
