Tribology is the science that studies the interaction of surfaces in relative motion, focusing on the mechanisms of friction, wear, fatigue, and corrosion, in the presence or absence of lubrication.
HEF focuses on analyzing defective parts brought in by clients from various industrial sectors (automotive, agricultural, mining, among others). Based on the problem description, a hundred parameters that could contribute to the failure are identified, such as: part material, lubrication, operating pressures and temperatures, operating atmosphere, operating speeds, geometry of the contact between parts, type of force applied, and surface properties present (hardness, roughness, structural defects, etc.).
Based on the parameters gathered, HEF seeks to understand the degradation mechanisms present in the client’s application, so that it can offer the best tribological solutions for the component. These may involve modifications that impact the design of the component or system in question, a change of materials, or the use of surface treatments.
Subsequently, an experimental phase can be conducted to qualify and characterize the performance of the proposed alternative solutions. For all these aspects, HEF has a variety of tribometers, as well as recognized experience in designing dedicated test benches, should this be necessary for the application. The objective of this experimentation is to replicate, as faithfully as possible, the operating conditions of the real application and the identified degradation mechanisms.
Dessa maneira, a HEF é capaz de oferecer a seus clientes soluções tribológicas que otimizem seus produtos e sistemas em eficiência e confiabilidade. A tribologia sempre esteve no centro de nossas atividades, e é essa expertise que colocamos à sua disposição.
