The incorporation of vegetable oils into the development of tread rubber formulation has been one of the alternatives to reduce the use of oil with high contents of aromatic polycyclics. Many studies suggest the substitution ...

This research has determined the parameters of powder metallurgy in order to use the wasted powder from the shot blasting process and transform it in components. The wasted was evaluated by its physical and micro-structural ...

Este trabalho apresenta um estudo das propriedades mecânicas e tribológicas de compósitos de alumina reforçados com partículas de nióbio obtidos pela técnica de sinterização por plasma pulsado (Spark Plasma Sintering – ...

Contamination by bacterial biofilms has a strong negative impact, especially when given on the surface of prostheses, implants, pins and other medical-surgical devices. In this study metal samples of Titanium cp and AISI ...

The surface modification of polymeric materials has led to significant design advances of new industrial applications, besides allowing the replacement of engineering polymers by lower cost materials. Thus, in the present ...
