1. Study of the AISI 52100 Steel Reuse Through the Powder Metallurgy Route Using High Energy Ball Milling
The AISI 52100 is a tool steel used in industry to produce bearings. After the end of its life cycle, it is remelted or discarded in deposits. The powder metallurgy rises as an alternative to recycle this material without any waste. The steps used to produce the AISI 52100 steel by powder metallurgy included: Machining with speed of 45 rpm, high energy ball

2. Microstructure and Mechanical Properties of Borided Inconel 625 Superalloy
ABSTRACT The Ni- based superalloy Inconel 625 is extensively used owing to its high strength, excellent fabricability, good weldability and outstanding resistance to high temperature corrosion against aggressive environments. However, despite its unique properties and extensive use, its wear resistance is in some cases unsatisfactory. In this study, Inconel

3. Correlation Between Fuel Lubricity and Vibration Signals Obtained in Ball-disc Analysis Using Fourier Transform
During the contact between metallic surfaces in mechanical systems, some dynamic characteristics present significant changes as the vibration signal patterns. The acquisition and characterization of these signals, by the use of Fourier Transform (FT), are non-intrusive tools in the evaluation of lubricity. This study aimed to evaluate dynamically the fuels l

4. Evaluation of the milling efficiency increase of AISI 52100 steel using niobium carbide addition through high energy ball milling
The AISI 52100 is a tool-type steel and is more often used in industry for the production of bearings. After the end of its life cycle, it is discarded or remelted, but both processes are considered expensive. Thus, the possibility of reusing this material through the powder metallurgy (PM) route is considered advantageous, since it transforms a waste into a

5. Estudo do desgaste e atrito em ensaios micro-abrasivos por esfera rotativa fixa em condições de força normal constante e pressão constante. / Wear and friction study in micro-abrasive wear testing by rotative fixed ball under conditions of constant normal force and constant pressure.
The micro-scale abrasive wear test by rotative ball has gained large acceptance in universities and research centers, being widely used in studies on the abrasive wear of materials. Two wear modes are usually observed in this type of test: rolling abrasion results when the abrasive particles roll on the surface of the tested specimen, while grooving abrasion

6. A DOE based approach for the design of RBF artificial neural networks applied to prediction of surface roughness in AISI 52100 hardened steel turning
The use of artificial neural networks for prediction in hard turning has received considerable attention in literature. An often quoted drawback of ANNs is the lack of a systematic way for the design of high performance networks. This study presents a DOE based approach for the design of ANNs of Radial Basis Function (RBF) architecture applied to surface rou

7. Investigação de novas rotas de tratamento térmico em aço para rolamento. / Investigation of new treatment routes for bearing steel.
Ao longo deste trabalho foi proposta uma nova rota de tratamento térmico para o aço AISI 52100, principal material utilizado na fabricação de rolamentos. Esta nova rota visa refinar a microestrutura de carbonetos presentes no material, com o objetivo de otimizar as propriedades mecânicas. Os tratamentos térmicos realizados conduziram a uma diminuição

8. Avaliação tribológica dos polímeros NBR, PTFE e PTFE gravitado em contato com aço AISI 52100
Retentores de baixo custo são comercialmente disponíveis de NBR, copolímeros insaturados de borrachas de nitrilo-butadieno que são mais resistentes aos óleos quanto mais altos forem seus teores de nitrila, à custa de uma menor flexibilidade. Em Engenharia de Petróleo, o desgaste dos retentores de NBR causa vazamento de fluidos e danos ambientais, prov

9. Consideration of stribeck diagram parameters in the investigation on wear and friction behavior in lubricated sliding
This paper deals with an experimental study of both wear and friction responses of lubricated sliding tests, considering both responses in Stribeck diagram. Analyses concerning the wear coefficient by Archard equation were also done. Tests were oil-bath lubricated, performed through a machine with devices for rotating pin-on-disk and reciprocating pin-on-pla

10. 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

11. Estudo do comportamento do coeficiente de desgaste e dos modos de desgaste abrasivo em ensaios de desgaste micro-abrasivo. / Wear coefficient and wear mode transition study in micro-abrasive wear testing.
This work presents a study on the behavior of different materials under the action of micro-abrasive wear. A micro-abrasive wear testing machine with fixed sphere was designed and constructed, presenting a mechanical configuration with differences with respect to those found in the literature (Gee et al., 2005). M2 tool steel and WC-Co P20 were used as testi
