Friction and wear behaviour prediction of HVOF coatings and electroplated hard chromium using neural computation

Improving Tribological Properties of Cast Al-Si Alloys through Application of Wear-Resistant Thermal Spray Coatings

“…Thick coatings (>1 mm) can be applied over a large area at very high deposition rates, compared with other coating processes such as electroplating, physical vapor deposition (PVD) and chemical vapor deposition (CVD). In addition, these environmentally friendly technologies have been identified as excellent alternatives (Ref 2,3) to the highly toxic (Ref 4) hard chrome plating (HCP) process, traditionally used in the automotive, aerospace, and mining industries. These surface treatments have been shown to have 5-10 times lower human health impacts and 30-50 times lower ecosystem impacts than the HCP process (Ref 5).…”

Hot corrosion behavior of detonation gun sprayed Cr3C2–NiCr coatings on Ni and Fe-based superalloys in Na2SO4–60% V2O5 environment at 900°C

“…HVOF-sprayed Cr 3 C 2 -NiCr and WC-Co coatings are widely studied as regards their wear-resistance behaviour, but now there is an increasing interest being shown in their application for protection against high temperature corrosion [1]. Thermal spray coatings, such as tungsten or chromium carbide coatings, seem to be an alternative to chromium plating, mainly when good wear resistance is required [2][3][4][5]. Cr 3 C 2 -NiCr coatings offer greater corrosion and oxidation resistance, also having a high melting point and maintaining high hardness, strength and wear resistance up to a maximum operating temperature of 900 • C [6][7][8][9][10][11].…”

Tribological and electrochemical behavior of thick Cr–C alloy coatings electrodeposited in trivalent chromium bath as an alternative to conventional Cr coatings

“…Substitutable materials mainly include Ni-W, Ni-P, Co-W, ternary or quaternary alloys and functionally graded deposits (FGDs) [5]. And new technologies mainly include high-velocity oxy-fuel (HVOF) [6], physical vapor deposition (PVD) [7] and trivalent chromium electro-deposition.…”
