High-speed steel (HSS) is commonly used in producing micro-cutting tools due to its excellent abrasive wear resistance, especially under high rotational speeds and low thermal activation conditions. Numerous studies have focused on enhancing the microstructural properties of HSS further improve resistance these micro tools. However, machining processes like grinding lapping are employed during manufacturing such as spade drills, milling cutters, taps. In processes, controlling rate crucial,...
Maskless electrochemical texturing (MECT) is an inexpensive and fast technique with great potential to produce surface textures on metallic surfaces at industrial scale. This work used MECT arrays of chevrons onto AISI 1045 steel surfaces. Block-on-ring tests using standard rings textured blocks investigated the effects full partial friction wear. Two normal loads (216.9 N 315.0 N) were applied investigate under mixed boundary lubrication regimes. Under lower load, increased wear rates. was...
This study investigates the microstructure and tribological behavior of Inconel 625 overlays applied via GMAW (Gas Metal Arc Welding) with without a 316LSi stainless-steel intermediate layer on top A36 steel. The microstructural characterization was conducted FESEM EDS. evaluated using tribometer in reciprocating configuration. results showed that wear rate weld overlay higher than it. However, no variations were observed terms hardness friction coefficient overlays. difference two coatings...
A well known phenomenon, the "built-up edge - BUE", occurs at chip/tool interface when multiphase materials are machined low cutting speeds. Under high compressive stresses, seizure prevents material from sliding over tool's rake face. Although many reports have been published on subject, studies of BUE phenomenon marked by a lack precision in determining its dimensions. This paper study geometry SAE 12L14 steel speeds with and without fluid. Three quick-stop samples were prepared for each...
This study aimed to improve a potentiodynamic-based methodological approach for characterising the tribocorrosion of ferritic stainless steel. Synergistic effects in systems have been widely investigated and debated under potentiostatic conditions. Because tests can ignore essential phenomena that are typically noticeable potentiodynamic (potential scanning), such as variations friction coefficient motivated by potential scanning, e.g., during active, passive, transpassive domains,...
The improvement of reciprocating engine efficiency, together with the responsible use worldwide energy resources and reduction pollutant emissions, are significant challenges to be addressed by automotive industry. Friction wear problems directly affect efficiency continue motivate study more effective lubricants. present work analyzes contribution alumina nanoparticles (Al 2 O 3 ) as additives in lubricating oil SAE grade 5W30 improve engines. Sliding friction tests were carried out varying...
<title>Abstract</title> Indentation fracture is a commonly employed technique for investigating solids' material properties and response to indentation. Subsurface lateral cracks are related the mass lost on materials presenting brittle behaviour, these usually observed in indentation experiments performed above critical loads. In this study, five microindentations were superimposed evaluate formation of under low loads, lower than load, soda-lime glass. Experimental tests carried out using...
