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. The Influences of Martensitic Transformations on Cavitation-Erosion Damage Initiation and Pitting Resistance of a Lean Austenitic Stainless Steel
This paper looks into the influences of martensitic transformations on the cavitation-erosion (CE) damage initiation mechanism and pitting corrosion resistance of a lean austenitic stainless steel. The ε and α' martensites are prime sites of CE damage initiation for this steel, whereas grain boundaries are more favourable damage initiation sites for other

3. Evaluation of erosion-corrosion resistance in Fe-Mn-Al austenitic steels
In this paper, the effects of Mn and Al against corrosion/errosion resistance of three samples of the Fe-Mn-Al austenitic alloys are evaluated. The samples have composition Fe-(4,9 ~ 11,0 wt. (%)) Al-(17,49 ~ 34,3 wt. (%)) Mn-(0,43 ~ 1,25 wt. (%))C, those were prepared in an induction furnace from high purity materials. The alloys were evaluated in a compose

4. Avaliação do efeito de particulados sólidos na eficiência de um inibidor de corrosão recomendado para meios salinos com CO2
The main problem on the exploration activity on petroleum industry is the formation water resulted on the fields producing. The aggravating of this problem is correlated with the advancing technologies used on the petroleum extractions and on its secondary approach objecting the reobtainment of this oil. Among the main contaminants of the water formation are

5. Erosion-corrosion wear of high nitrogen stainless steels in a slurry. / Estudo do desgaste erosivo-corrosivo de aços inoxidáveis de alto nitrogênio em meio lamacento.
Os processos de erosão-corrosão são comumente encontrados em tubulações, válvulas e outros componentes usados na indústria química, petroquímica e na exploração de minérios. Quando a corrosão e a erosão atuam conjuntamente, os mecanismos de dano são complexos e em geral as perdas de massa associadas com esta combinação de processos são maio

6. Remote sensing and geoprocessing techniques applied to determine new urban zones in the basin of Una River: São Sebastião. São Paulo State. / Sensoriamento Remoto e Geoprocessamento aplicados ao zoneamento urbano da Bacia do Rio Una: Municipio de São Sebastião, SP
This study presents a terrain zoning to characterize, hierarchize and quantify its capability to the urban development, considering the physics, biological and anthropic regional aspects. The study area size is 120 sq km and it takes part of the Una river basin, in the Sao Sebastiao county, located in the North Litoral of São Paulo state, Brazil. The study
