1. Efecto de los parámetros de aplicación en recubrimientos de Ni-Cr-B-Fe-Si obtenidos por Flame Spray
ABSTRACT Surface damage of components in service is an issue of great industrial interest because of the costs associated to the replacement of certain critical components. There are several techniques to generate coatings, which provide increased resistance to a particular type of surface damage. In this way, it is achieved surface protection to different s

2. Effect of processing on microstructure and properties of CoCrMoSi alloy
CoCrMoSi alloys microstructure is affected by processing and their properties have been associated with the high volume fraction of Laves phase. However, not much has been reported on the effect of structure refinement and morphology on the properties of these alloys. This paper evaluates a CoCrMoSi alloy processed by centrifugal casting and Plasma Transferr

3. Influência da adição de nanopartículas de TiO2 na obtenção de compósitos a base de liga AA2014 fabricada via metalurgia do pó / Influence of the addition of TiO2 nanoparticles in the composites formation based AA2014 alloy manufactured by powder metallurgy
Aluminum matrix composites and its alloys, especially AA2014, are widely used in automotive and aeronautics applications. The properties of this are very influenced by hardening treatment, however its use is limited at temperatures above 150C due to loss of properties caused by the growth of precipitates at this temperature. The addition of a new phase, fine

4. Microstructural control of Co-based PTA coatings
Cobalt-based alloys are widely used as hardfacing materials when wear resistance is required at room temperature or high temperature applications. However, their performance is a consequence of their microstructures that depends on the processing conditions. This work focused on the influence of solidification rate on the structure development by processing

6. Efeito da substituição do molibdênio pelo nióbio e nióbio-boro em aços Hadfield no desempenho ao desgaste abrasivo
The aim of this research was to allow the development of these types of alloys for wear resistance, in order to promote the application of these alloys in economic terms and mechanical properties. Nowadays, with the high prices of some materials, mainly those with molybdenum, both ferro-alloy as oxide, there is a bigger and bigger necessity in to develop new
