                  2,Plasma Spray Brief Introduction                 plasma spraying machine using argon, nitrogen, hydrogen as working gas, the ionizing high-temperature melt the powder into plasma forming gas, expands and is accelerated through a shaped nozzle, creating velocities up to MACH 2. Temperatures in the arc zone approach 36,000°F (20,000°K)   Many kinds of materials can be used by plasma spray, especially some high-melting- point materials such as refractory metal, ceramics, metal ceramics and other special function materials.   High flame stream temperature and high jet speed, can spray out high quality coating, especially high quality ceramic coating.   Applications   1.Provide protection against high temperatures, corrosion, erosion, wear   2. Change the appearance, electrical or tribological properties of the surface, replace worn material   3. Sprayed on substrates of various shapes and removed, free-standing parts in the form of plates, tubes, shells, etc.   4. Powder processing (spheroidization, homogenization, modification of chemistry, etc.)

    3,HVOF Spray Machine Brief Introduction         he principal of SX-5000 HVOF equipment is: the mixture gas of oxygen and fuel gas is sent to the burning area of spray gun exit under high pressure. Then the burning gas is accelerated to form a supersonic flame with the help of peripheral compressed air. The spraypowder is sent into burning flame and make a functional coating.SX-5000 consists of spray gun, powder feeding machine, control system, heat-exchanger system and pipeline system. It’s a compact equipment with the traits of easy-operating, stable working performance, low fuel consumption and high-quality coating.   HVOF coating equipment/ Tungsten carbide HVOF coating equipment        1.Brief Introduction of  HVOF coating equipment/ Tungsten carbide HVOF coating equipment   (1)high temperature resisting coating using argon, nitrogen, hydrogen as working gas, the ionizing hightemperature melt the powder into plasma  forming gas, expands and is accelerated through a shaped nozzle, creating velocities up to MACH    (2) Temperatures in the arc zone approach 36,000°F (20,000°K)   2.Characteristics of HVOF coating equipment / Tungsten carbide HVOF coating  equipment     (1)high temperatu reesisting coating can spray all kind of Metal powder, such as Ceramic powder ( Chrome oxide, Titanium oxide, Aluminum  oxide, aluminum titanium oxide,  Zirconium oxide powder, etc.), Alloy powder (WC-Co, Cr3C2 NiCr), Chrome, Titanium,  Silicon powder, etc.        (2) Inert gas can be used as working medium to reduce the oxidation of spraying particles.   (3) The coating can get high bond strength, low porosity. You can get accurate coating by controlling  technological parameter.   3.Applications of HVOF coating equipment / Tungsten carbide HVOF coating  equipment   (1) Provide protection against high temperatures, corrosion, erosion, wear-resisting effect,prolong lifetime.
