Corrosion resistance of HVOF-sprayed coatings for hard chrome replacement

, 2006
HVOF-sprayed coatings (WC-17Co, WC-10Co-4Cr, Co-28Mo-17Cr-3Si) and electrolytic hard chrome (EHC) coatings corrosion resistances have been compared through electrochemical polarization tests (0.1 N HCl, 0.1 N HNO3) and Corrodkote test.

Turn Milling of Inconel 718 Produced via Additive Manufacturing Using HVOF and DMLS Methods

Journal of Manufacturing and Materials Processing
Additive and coating technologies, such as high-velocity oxy-fuel (HVOF) thermal spraying and direct metal laser sintering (DMLS), often require extensive post-processing to meet dimensional and surface quality requirements, which remains challenging for

High Velocity Oxy-Fuel (HVOF) as a materials test method for simulating aerothermal effects

, 2022
High Velocity Oxygen-Fuel (HVOF) is a member of the thermal spray process family in which a mixture of oxygen, fuel, and compressed air are continuously combusted and the resulting flame is accelerated through a nozzle to achieve high gas velocities ...

Diagnostic tools for HVOF process optimization: Dissertation

, 2005
In the thermal spray process the coating is built up from lamellas formed by rapid solidification of the melted or semi-melted droplets attached to the substrate. A typical structure for the coating is a pancake-like lamellar structure, where the flattening stage and adhesion between the lamellas, together with the coating material itself, define the ...
