The high-pressure die-casting process is growing since it a cost-effective solution in the production of lightweight parts for variety industries. Nevertheless, harsh working conditions die lead to premature failing and poor quality produced parts. Lubricants are applied cooling surface create protective film minimize wear. However, high temperature during casting makes difficult lubricant reach due Leidenfrost effect. In this study, effectiveness newly developed ester-based lubricants...
This study evaluates the effect of vibration assisted ball burnishing method on surface integrity maraging C300 steel surfaces printed by additive manufacturing with Selective Laser Melting (SLM) technology. The analysis contemplates variations in tool preloads and applied force. analyzed material is based as-built (AM), machined (M) (VABB) states. Surface roughness was evaluated to assess topographical conditions both before after process. Microstructure mechanical deformation were Scanning...
The replacement of conventional lubricants with esters is an alternative to provide a low environmental impact and at the same time excellent lubricity features, high solubility additives, good viscosity index, volatility, thermal stability. Friction modifiers antiwear/extreme pressure additives are extensively used save energy increase operational life in machine components. In this study, Group IV base oil containing ester various benchmark friction and/or measured evaluate influence on...
Numerous simplified numerical models have been established to optimize the ball burnishing of steel surfaces. Nevertheless, their conceptualization has not considered tool–part interaction, leading an unsatisfactory process parameterization. As a solution, structured simulation defined that reproduces this interaction by several friction coefficient approximations. This study provides tribological inputs (friction and initial surface conditions) model, adapting it pre-textured martensitic...
Nanosized aluminophosphate AlPO4-18 (AEI-type topology) crystals with monomodal particle size distribution were synthesized in the form of stable colloidal solutions and used for supported growth thin oriented films on silicon wafers.
Burnishing is a plastic deformation process that reduces roughness while increasing hardness by introducing compressive residual stresses near the surface zone. These improvements will depend mainly on two fundamental variables: applied load and friction derived from tool-surface interaction. Nevertheless, microstructural differences in materials have not yet been considered within this This leads to generalization of can result failure industrial components. Therefore, aim work study...
The use of lightweight materials, such as ultra-high-strength aluminium alloys, is in high demand the automotive and aerospace industries where weight savings are critical. tool materials used for high-speed cutting these alloys subjected to severe conditions that promote premature failure tools. application polycrystalline diamond (PCD) coatings provides tools with increased mechanical thermal fatigue resistance improved tribological performance. Despite good properties, their cost remains...
Press hardened components have become widespread in the automotive industry structural and crash-resistant applications, thanks to combination of complex shapes high mechanical properties obtained. However, press hardening coated boron steel results severe adhesive-based wear, with tool maintenance being required as few 3000 cycles. The current industrial implementation is defined work around this phenomenon. While aspect has been studied by different authors, most literature deals...
