HVOF Gun HVOF stands for High-Velocity Oxy-Fuel . In this high-velocity oxy-fuel is supplied by the gun. HVOF Gun  required a very high velocity for the coating process. This high velocity is used to propel the particles at supersonic speed before impact onto the substrate. In the spray process high combustion pressure and high velocity of gas and particle resulting in high coating quality. Two types of Hvof on basics fuel Liquid Fuel Gas-Fuel HVOF Gun Application High density. Typical coatings have less than 2% porosity and some coatings as low as 0.5% porosity.  High bond strength. For example, typical carbide coatings sprayed with HVOF exhibit bond strengths in excess of 69 MPA (10,000 psi). Other coating materials sprayed with HVOF have significantly higher bond strengths than the same materials applied using other atmospheric thermal spray processes such as air plasma spray.   Optimum Hardness. A 12% tungsten carbide / cobalt coating will hav...

Twin Wire Arc Spray Gun Twin Wire Arc Spray Gun is a gun in which two wires   anode and cathode respectively fed into the gun. When two wires touched it creates a spark and causes heating of those wires. Through which molten metal is poured onto the subject. The Twin Wire Arc process is a common commercial thermal spray process. It uses abrasive as a wire only other abrasive can't be used in Arc Spray Gun . Twin Wire Arc  the coating is applied using a spray torch, which brings two electrically energized feedstock wires together. When the wires cross, an arc, similar to a welding arc, forms between the wire tips and causes them to melt. A gas stream injected behind the arcing wire tips atomizes the molten feedstock material and propels it downstream. When molten droplets of the feedstock material encounter the substrate the droplets flatten, solidify, and form a coating containing the characteristic lamellar structure associated with thermally sprayed materials....

Zinc Spray Gun Zinc Metallizing  is a versatile process which melts Zinc or Zinc   Alloy metals, and then rapidly propels the molten Zinc particles onto a prepared substrate, creating a lamellar or layered coating. Metallizing, or Thermal Spraying as it is often called, is a highly effective and proven method of corrosion prevention, giving galvanic as well as barrier coating protection to iron and steel. How does Zinc Coating work? Most protective coating systems for steel function acting as a barrier between the steel and the corrosive environment. If these passive and permeable barriers are damaged or penetrated, moisture and oxygen can reach the steel causing rust and eventual coating failure. A zinc metalized coating also offers barrier protection; however, the electrochemical relationship between zinc and steel allows a zinc coating to give cathodic protection as well. A zinc metalized coating will protect the steel galvanically: it will corrode in preference to s...

Metalizing Gun Metalizing is a general process of metling metal in molten form to have thermal spray coating process is used for coating metal on product surfaces. The resultant metallic coatings can be used for protective, Anti-corrosive, decorative or functional purposes. These coatings are also known to be long-lasting, effective and highly versatile. Three Types of Spraying Techniques: Electric arc spray Combustion powder spray Combustion wire spray Electric Arc Spray is this process, we utilize two metallic wires that are electrically charged with opposing polarity as the coating feedstock. This will cause them to throw a molten arc between each other. Then injection of inert gas or high velocity air to trigger an atomization of the now-molten material and propel onto the substrate to form the coating. If you opt for the electric arc spray process, we can spray any type of metals which have melting points below 5540°C. Depending on the equipment being us...
