The paper presents the results of research aimed at increasing life moulds and cores for high-pressure aluminium casting. castings produced are intended automotive industry. Local impulse heating was applied to surface base material Uddeholm Dievar moulds. Three rates were used. After treatment, structural analysis performed. PVD coating nACRo3 treated in this way. Coating deposition performed ...

Considering the influence of non-equibiaxial stress state and initial residual strain on compressive buckling ceramic layer, a quantitative characterization method damage generated at interface between top coat bond in thermal barrier coating based uniaxial compression was developed. It verified by axial tests single crystal specimens with EB-PVD after undergoing various isothermal oxidation ti...

AIMS To identify variations in posterior vitreous detachment (PVD) and establish a clinical classification system for PVD. METHODS 400 consecutive eyes were examined using biomicroscopy and vitreous photography and classified the PVD variations-complete PVD with collapse, complete PVD without collapse, partial PVD with thickened posterior vitreous cortex (TPVC), or partial PVD without TPVC. ...

Coatings by physical vapor deposition (PVD) have become highly relevant due to their wide range of applications and the rapid rate coating formation. In this work, AISI steel 1045 was coated with two layers, Ni Co using PVD technique. Each deposited a thickness 1 ?m. After applying coatings, post-treatment applied in an AC plasma reactor boron nitride blank Ar atmosphere at pressure 3 Torr, 0.3...
