(PDF) Solid particle erosion of HVOF sprayed WC-Co

Solid particle erosion of HVOF sprayed WC-Co/NiCrFeSiB coatings. Pawan Sapra. IntroductionErosive wear is caused in the solid bodies by the action of sliding or impact of solids, liquids, gases or a combination of these [1]. Manifestations of solid particle erosion in service usually include thinning of components, a macroscopic scooping Alternative metallic matrices for WC-based HVOF coatings Nov 25, 2020 · 1. Introduction. WC-CoCr hardmetals have long been employed as feedstock for thermal spray processes, in order to manufacture wear- and corrosion-resistant coatings [].These hardmetal compositions stem from bulk WC-Co metalworking tools, which, in turn, have been known at least since 1923, as reviewed by Ettmayer et al. [].The amount of metallic matrix in WC-based hardmetals for

  • BenefitsApplication & MaterialsProcess DetailsHVAF Spray Thermal Spray Coatings Machine Part All of these advantages make HVAF coatings the most abrasion, wear and corrosion resistant. This low spray temperature also makes HVAF the most ductile coating; aiding in cavitation damage protection. HVAF coating technology is the combustion of propane in a compressed air stream. Like HVOF, this produces a uniform high velocity jet. Component repair using HVOF thermal spraying Semantic Abstract The high velocity oxy-fuel (HVOF) thermal spraying technique has been widely adopted in many industries due to its flexibility and cost effectiveness. It is normally used to apply coatings to components to protect against wear, heat and/or corrosion, but also has potential to build up worn components. The main objective of this study was to optimise the HVOF spraying technique for the

    Correlation between tribological measurements and

    wear resistance. In the field of elastomeric seals several approaches have been used, such as changing the system configuration, designing new cross section shapes [13], texturing the contact surface and applying coatings. Furthermore, in 1979 Gent et al. [5] studied the wear of HVOF Spray Thermal Spray Coatings Tungsten Carbide HVOF Spray Solutions. HVOF is our most versatile spray solution. Almost any part is a good candidate for HVOF, so it is up to the customer to determine if the additional corrosion and wear protection is required over flame, arc or plasma spray. HVOF excels at thinner coatings

    High Velocity Oxygen Fuel (HVOF) coating - Services

    High Velocity Oxygen Fuel (HVOF) coating. High-Velocity Oxygen Fuel (HVOF) coating is a thermal spray coating process used to improve or restore a components surface properties or dimensions, thus extending equipment life by significantly increasing erosion and wear resistance Microstructure, Wear and Corrosion Properties o f HVOF coating resulted in low porosity, better wear resistance, and superior hardness. Wang et al (2009), investigated the performance of the structure of WC-12Co coating that is deposited by HVOF process, moreover, authors found better wear resistance compared to other coating especially coating on

    Sliding wear behaviour of conventional and nanostructured

    Jul 01, 2005 · However, the effects of powder morphology, type of HVOF spray system and spray parameters have all been shown to affect the coating microstructure and, in turn, the wear resistance , , , . It is well established that thermally sprayed WCCo coatings exhibit complex, multi-phase microstructures, with a significantly lower volume fraction of TOPCOAT® WCR - Griekspoor Thermal CoatingsWear-resistance and hardness are excellent. During the lifetime of the coated product there is minimal wear on all surfaces. The tribological characteristics and lubrication remain consistently high. For extra corrosion protection Griekspoor can apply a nickel based superalloy intermediate coating under the WCR coating.
