Plasma Electrolytic Oxidation (PEO) and Hard Anodizing (HA) coatings are investigated on an Additively Manufactured (AM) Al10Si1Mg alloy obtained via Direct Metal Laser Sintering (DMLS). Results compared to those for a conventional A361 cast alloy. Findings revealed that the microstructure of AM alloy, consisting α-Al cells enclosed in Si network, produces more uniform –in terms morphology, thi...

Simultaneous realization of superior mechanical and antifouling properties is critical for a coating. The use stereoscopic polysiloxanes in place linear to fabricate coatings can combine organic inorganic materials, i.e., they exhibit both high hardness wear resistance from components as well the flexibility tunability components. This strategy used prepare hard yet flexible or polymer-ceramic ...

Distinct improvement in adhesion of diamond coatings on hard metal substrates was achieved by following substrate surface pretreatment [I]: First WC was removed from the substrate surface by etching with Murakami solution (K3[Fe(CN)6] in KOH), after which the Co binder network was etched with H2S04/H202 solution. Then diamond coatings were deposited on the substrates by hot-filament CVD. Appare...

a plain strain analysis of frictional rolling contact on an elastic graded coating is presented in this paper. finite element method is applied to gain an understanding of the stresses and contact zone properties caused during rolling contact. the effects of friction, material stiffness ratio and coating thickness on stresses in contact zone and coating/substrate interface are studied. shear mo...
