Tungsten Carbide Spray Coating
Tungsten Carbide Coating is spread by a thermal spray coating process. A tungsten carbide coating devoted by the high velocity oxy-fuel (HVOF Gun) technique has a high possibility of success in substituting chrome plating. Typical enactment features of the tungsten carbide coating (WC coating) can be adjusted by changing the specifications of the tungsten carbide powder & binding mechanism– usually Cobalt. Divergences in grain size & temperature of application can largely dissemble bond resilience, wear characteristics, & defenselessness to corrosion & decay; We authorize the tailoring of HVOF tungsten carbide coatings to approximate typical application necessities.
Tungsten carbide powder is commonly located as a good powder that is gray in color in its essential form. Yet, it is constructed & encouraged through sintering to construct jewelry, cutting instruments, & industrial machinery. When mixed with a small amount of metallic powder (typically Co, Cr, or Ni) it can be curved into carbide coatings comprehended for powerful resistance to abrasion, corrosion, & wear.
Tungsten Carbide Coating Machine
Tungsten Carbide and alloy powders are delivered into a combustion chamber where they are melted & accelerated to supersonic speeds in the Tungsten carbide coating machine. These semi-molten bits are deposited on the substrate, resulting in quick cooling and the formation of a coating layer with extraordinarily high density and binding strength. Tungsten carbide Coating Machine offers mechanically bonded coatings that give corrosion, erosion, abrasion, & sliding wear resistance to coated components.
Tungsten Carbide Thermal Spray Coating
Tungsten Carbide Thermal Spray coatings deliver wear surfaces to new & rebuilt parts for assorted industries. Their wear resistance is acquired by combining small tungsten carbide particles into a metal matrix.
In metal alloys, the accumulation of chromium is usually acceptable to propose some resistance to corrosion. This is also a truth with thermal spray coatings. A straightforward accumulation of a rare percent of chromium in the metal matrix delivers the coating with sufficient corrosion protection to ensure an acceptable implementation in many sarcastic environments. Nonetheless, it is not just the accumulation of chromium that delivers corrosion resistance, though the strategy & the process by which a coating is incriminated will even affect the coating structure & thereby the interpretation & the erosion resistance of the consequent thermal spray coating.
Tungsten carbide thermal spray coatings are the principal & the considerable determined kind of wear-resistant coatings. They reach their wear resistance from a considerable portion of tungsten carbide in a scaffolding held concurrently by a metal binder. Hardened tungsten carbide particles & their large importance fraction equip the wear resistance for these thermal spray coatings. The softer metal binder emerges then as a diluent that will deform the wear properties of the coatings, This is certainly the truth, but as they are required to hold the structure concurrently, the metal binders can & do play an essential role in generating secondary properties for the coatings, like their automatic properties as well as their resistance to corrosion.
HVOF Tungsten Carbide Coating
tungsten carbide coatings (WC coating) involved high velocity oxygen-fuel spray gun (HVOF) thermal spray procedures & were tested broadly as a conceivable expedient for hard chrome plating. These coatings do not pose the environmental risks of chrome plating, & maintain the added benefit of requiring fewer processing steps & time to produce. Testing has consistently shown that when functioning accompanied by proper materials, application techniques, & parameters, the HVOF coatings deliver narrower fatigue debit, more corrosion resistance, & adequate wear resistance than chrome plate. The improved enactment characteristics & reduction in application time offer significant opportunities for manufacturers & operators; whether eliminating the increasing health & environmental liabilities of a chrome plating facility, or reducing the maintenance requirements of assorted systems & equipment.
As an impact of positive test data acquired in comparing HVOF coatings to chrome plate, a number of aircraft applications are now approved for new manufacture, overhaul, and rework. These applications include highly loaded, fatigue-critical items like main landing gear cylinders, axles, and truck beam pivot pins. Because some components such as the main cylinder are in sliding contact with a hydraulic seal, there is concern for the seal life or the potential for impulsive leakage.
Studies manipulated on seal wear with HVOF thermal spray coatings have demonstrated that seal life can be enhanced when finer surface finishes are employed than those traditionally utilized on chrome plates. Removals of 2 to 4 times in the Ra value commonly utilized with chrome have been demonstrated to be effective. In areas where a chrome finish would be determined at 0.40 m (16 in) Ra or finer, HVOF finishes of 0.20 m (8 in) Ra or even 0.10 m (4 in) Ra or finer are alluring to improve seal life. While this appears contrary to concerns that extremely fine finishes do not provide acceptable oil retention to lubricate a seal adequately, testing and experience prove otherwise.
These adequate finishes are acquired by traditional grinding methods utilizing diamond wheels, or by additional polishing. Because of the increasing demand for low Ra values on the HVOF coating process, the use of superfinishing equipment to increase established grinding was analyzed. This paper summarizes a study embarked to estimate the surface finish properties of HVOF tungsten carbide coatings approximated to comparable finishes on chrome plate. Further finish improvements attainable by the use of superfinishing equipment are also documented. Also included are reports and data from various tests and service evaluations of HVOF coatings.
