Abstract

This study presents the test results of Ti-46Al-7Nb-0.7Cr-0.1Si-0.2Ni alloy isothermal oxidation with regard to a coating of SiO2 deposited by the sol-gel method. The oxidation test was carried out in air at 900°C. The SiO2 coating is not an effective and stable diffusive barrier, which would considerably improve oxidation resistance of Ti-46Al-7Nb-0.7Cr-0.1Si-0.2Ni alloy.

Abstract

Electrochemical polishing of metals and alloys is one of the most currently used finishing treatments, covering metallic biomaterials with complicated shapes (coronary stents, prostheses, etc.). A standard electropolishing (EP) process has been recently modified by including a magnetic field, and called the magnetoelectropolishing (MEP). Many surface properties and even mechanical features may be modified and improved by MEP. The changes are concerned with the surface film composition which undergo a modification. For the present studies, X-ray Photoelectron Spectroscopy (XPS) analysis was applied to measure the surface film composition on AISI 316L stainless steel. In conclusion both Cr-X/Fe-X compounds ratio as well as Cr/Fe total ratio of the 316L steel after EP and MEP were calculated and compared to reveal the advantage of the magnetic field used.

Abstract

The microstructures, water absorption as well as blistering was studied for bi- and tri- axial glass fibre vinyl ester and polyester -matrix laminates coated with gel coat layer and uncoated. The effect of manufacturing technique on water sorption characteristics was considered. It was found that water sorption characteristics of GFRP depend on manufacturing methods. The least water intake was found for specimens having perfect microstructure due to manufacturing by infusion process. Water sorption saturation value was reached after ca. 50 days of accelerated test at 70°C and was found to correspond to 250 days conditioning at 20°C. Blistering evolution was illustrated and SEM images shown corresponding to degradation of the gel coat layer and the laminate during the exposure in water.
