On the tribological behaviour of metal/ceramic and metal/metal couplings

, 2011
Corrosion, wear or the combined effects of these failure modes cost the industrial economies hundreds of billions of euros each year. One of the more effective ways to reduce damage due to corrosion and wear is to treat, or “engineer” the surface, so ...

Determination of mechanical and fatigue properties of HVOF-sprayed coatings

, 2022
S.233-238High velocity oxy-fuel spraying (HVOF) is the most suitable process in the group of thermal spray processes for realizing the functionality of hardmetals on the surfaces of large parts. Before HVOF-sprayed hardmetal coatings can be used reliably

Demonstrating circularity in thermal spraying: Converting waste to wealth

Materials Today Sustainability
Typically, 40–60 % of the injected powder feedstock in most thermal spray processes ends up as overspray waste and is a prominent technology drawback.

HVOF-Sprayed Nylon-11 + Nanodiamond Composite Coatings: Production & Characterization

, 2008
High velocity oxy-fuel (HVOF) combustion spraying has previously been shown to be a viable method for depositing polymer and polymer/ceramic composite coatings. The addition of hard particulate reinforcing phases to soft polymeric matrices should improve

Microstructure and elevated temperature wear behavior of HVOF-sprayed SS304L stainless-steel coating

Discover Applied Sciences
The paper aims to investigate the performance of the SS304L stainless steel coating on wear properties by varying load, temperature and velocity. Stainless-steel coatings were fabricated by high-velocity oxy-fuel spraying (HVOF) on superfer800.
