1. Wear behavior of Diamond-like Carbon Deposited on Ti6Al4V Prepared with Surface Mechanical Attrition Treatment
Surface modification by deposition of hard coatings is a way to overpass the poor wear resistance of some metallic materials and one potential material is the Diamond-Like Carbon (DLC). We investigated the wear behavior, and the adhesion of the DLC deposited on a Ti6Al4V (Ti64) alloy after Surface Mechanical Attrition Treatment (SMAT). The SMAT was applied u

2. The Lubricity Analysis of Cutting Fluid Emulsions
The new generation of cutting fluids should have some characteristics, such as low toxicity and biodegradability. A bio-cutting fluid emulsion are an excellent option because they present those properties, as well as good mechanical performance. The present study aims to investigate the lubricity of O/W emulsions (cutting fluid emulsion), varying the concent

3. Coolant lubricity and coolant-lube compatibility with regard to slideway behavior
Coolants are widely used in industries for metal cutting operations. Though there are varieties of coolants available, the most widely used are water-soluble coolants because of their low cost and better heat dissipation compared to straight cutting oils. In the present investigation, amongst the various causes, which deteriorate the coolant, the role of har

4. PROPRIEDADES MECÂNICAS E TRIBOLÓGICAS DE AÇO AUSTENÍTICO 304 SUBMETIDO À NITRETAÇÃO POR: IMPLANTAÇÃO IÔNICA E IMPLANTAÇÃO IÔNICA POR IMERSÃO EM PLASMA.
The aim of this work is to characterize the mechanical and tribological properties of AISI 304 austenitic stainless steel submitted to N+ ion implantation and Nitrogen plasma immersion ion implantation (PI3). The ion implantation conditions were to obtain a plateau distribution of N íons in atomic concentrations of up to 27. The PI3 nitretation were perform

5. Influence of loading, contamination and additive on the wear of a metallic pair under rotating and reciprocating lubricated sliding
This paper deals with an experimental study of wear and friction responses from lubricated sliding. Tests were carried out using a tribometer having devices for both continuous and reciprocating motion. The tested specimens were pins of AISI 52100 steel and counter-faces of AISI 8640 steel. The lubricant was paraffin mineral oil, VI 100. The presence of addi

6. Non linear signal analysis applied to friction force identification in tribological tests / Identificação da força de atrito através de análise de sinais não lineares em ensaios tribológicos
When the surfaces of two elastic bodies present relative motions under certain amount of contact pressure the mechanical system can be instable. Experiments conducted on elastic bodies under friction forces shown that the dynamical system is self-excited by the non-linear behavior of frictional forces. The main objectives of this thesis are the study of the

7. Non linear signal analysis applied to friction force identification in tribological tests / IdentificaÃÃo da forÃa de atrito atravÃs de anÃlise de sinais nÃo lineares em ensaios tribolÃgicos
Quando as superfÃcies de dois corpos elÃsticos em contato apresentam movimento relativo, o sistema mecÃnico pode se tornar instÃvel. Experimentos conduzidos com corpos elÃsticos em contato mostram que o sistema à um sistema auto excitado devido à caracterÃstica nÃo linear da forÃa de atrito. Os objetivos principais desta tese sÃo o estudo do campo
