João Luiz do Vale | Engineering and Technology | Best Researcher Award

Dr João Luiz do Vale, UTFPR, Brazil

João Luiz do Vale, born on June 24, 1980, in Curitiba/PR, Brazil, is an accomplished mechanical engineer specializing in tribology and materials engineering 🌟. He holds a PhD in Mechanical Engineering from the Universidade Tecnológica Federal do Paraná (UTFPR) 🎓, where he is a dedicated professor 🧑‍🏫. With extensive experience in the metal-mechanical industry, João has contributed significantly to research on surface treatments and the tribological behavior of cast irons, as well as the application of finite element methods in machine elements 🛠️.

Publication profile



From 2014 to 2016, He pursued a PhD in Mechanical and Materials Engineering at the Federal University of Technology – Paraná (UTFPR), Curitiba, Brazil, focusing on the influence of cast iron microstructure on folded metal occurrence and the tribological behavior of honed surfaces 🏫. My dissertation, supervised by Giuseppe Pintaude with co-advisor Carlos Henrique da Silva, emphasized friction, wear, and honing 📚. Prior, He completed a Master’s degree (2013-2014) on the tribological behavior of PTFE sliding against stainless steel without lubrication, also at UTFPR, under Carlos Henrique da Silva’s guidance 🛠️. Since 2014, I’ve been a full-time professor at UTFPR, teaching courses such as Technical Drawing and Mechanical Elements 📐👨‍🏫.

Research focus

João Luiz do Vale’s research primarily focuses on tribology, the study of friction, wear, and lubrication of interacting surfaces in relative motion. His work encompasses a variety of applications, including the performance of lubricants, the tribological behavior of different materials, and the impact of additives. He has extensively studied the friction coefficients, wear resistance, and tribological properties of materials like graphite and bronze-filled PTFE, as well as cast irons used in cylinder liners. His research contributes to improving material performance and durability in mechanical systems, particularly in automotive and industrial applications. 🛠️🧪🔍
