Influência da temperatura de pré-aquecimento sobre a morfologia e ciclos térmicos de revestimentos YSZ
(Universidade Tecnológica Federal do ParanáPonta GrossaBrasilPrograma de Pós-Graduação em Engenharia MecânicaUTFPR, 2015-09-03)
High temperature resistant coatings, such as thermal barrier coatings (TBC), are composed of a ceramic layer (Top Coat) deposited on a metallic layer Bond Coat, these coatings are normally applied by thermal spray techniques ...
Analysis of the life of cemented carbide drills with modified surfaces

Promising duplex coatings for tribological applications at elevated temperatures
(Universidade Federal de Minas GeraisUFMG, 2001-04-09)
It has already been reported that duplex coatings, consisting of plasma nitriding of steel substrates and subsequent deposition of hard coatings by PAPVD (plasma-assisted physical vapour deposition), can improve both wear ...
TiAlN coatings deposited by triode magnetron sputtering varying the bias voltage
(ELSEVIER SCIENCE BV, 2011)
TiAlN films were deposited on AISI O1 tool steel using a triode magnetron sputtering system. The bias voltage effect on the composition, thickness, crystallography, microstructure, hardness and adhesion strength was ...
