1. Revestimentos de liga de nÃquel depositados pelo processo TIG com alimentaÃÃo de arame frio: aspectos operacionais e metalÃrgicos / Nickel based alloys weld overlay deposited by gtaw cold wire feed: operational and metallurgical aspects
The weld overlay with nickel-based alloys is an interesting alternative for the construction and repair of equipments for applications in severe corrosive medium, allowing reach the desirable characteristics (corrosion resistance) with a significant reduction of cost. In this context, the GTAW cold wire feed process can be a good option for overlay depositio

2. Análisis de perfiles de difracción de rayos X de una aleación Cu-8% en peso de Cr obtenida por medio de aleado mecánico
This work studies the evolution of the microstrucutre of a mechanically alloyed Cu-8 wt. % Cr powder mixture by X-Ray profiles analysis. The process was carried out using a SPEX8000D upon mix with stainless steels containers and balls, keeping a constant powder to balls weight ratio of 10. Increasing the milling time, crystallite size and stacking fault ener

3. Solid particle erosion of plasma sprayed ceramic coatings
Thermal spraying allows the production of overlay protective coatings of a great variety of materials, almost without limitations as to its components, phases and constituents on a range of substrates. Wear and corrosion resistant coatings account for significant utilization of thermal spray processes. Besides being a means to evaluate the coating tribologic
