  Development of wear resistant and dry self-lubricating coatings on sintered steels from polymer-derived ceramics (PDCs). [BRAGECRIM], Descrição: BRAGECRIM (UFSC/Brazil + UNIVERSITY OF BAYREUTH/Germany It is estimated that about 34% of all energy used in industrial countries is wasted to overcome friction. In addition to energy loss, the heat generated by the friction affects negatively the performance of the mechanical system. High friction results in higher wear and more than 30% of the production in industry goes to replace worn out products with new ones. Much is studied to overcome these problems in industry and to develop components which are less susceptible to friction and wear. In a reciprocal manner friction affect also day-life products (e.g. refrigerator compressors) which work under pressure and metal-metal contact is almost unavoidable. Nowadays many innovative techniques are applied to increase the working-life of a component. Many achievements are already reached but still optimized energetic efficiency is pursued. Some current solutions for the problem of friction are coating the mechanical parts with solid lubricant films by vapour deposition techniques or to produce parts with a dry self lubricating material (material with solid lubricant particles dispersed in its volume). It is also possible to coat the parts with a layer of dry self-lubricating material. Each method has its own pros and cons. The coating feature can be scratched off the surface whether the self-lubricating surfaces are still under development and much need to be done, in addition production of solid lubricant coated parts involve many steps and high-costs equipment and materials. In order to increase the energetic efficiency of the products, at the same time that the productivity of industry is increased, a new method is proposed to generate hardened surface on metals as well as a new possibility to generate dry self-lubricating components. Applying the new technology of Polymer Derived Ceramic (PDC) on the manufacturing of metal parts improvements in energy efficiency and endurance of product life-cycle are expected.. , Situação: Concluído; Natureza: Pesquisa. , Alunos envolvidos: Graduação: (2) / Mestrado acadêmico: (4) / Doutorado: (4) . , Integrantes: Daniel Auri Schaefer - Integrante / Mateus Lenz Leite - Integrante / Nilda Martins - Integrante / Martin Seifert - Integrante / Günter Motz - Integrante / Aloisio Nelmo Klein - Coordenador / Priscila da Costa Gonçalves - Integrante / Tercius de Domenico Justus - Integrante / André Prette - Integrante / Cristiano Binder - Integrante / José Daniel Biasoli De Mello - Integrante / Dachamir Hotza - Integrante / Gisele Hammes - Integrante / João Batista Rodrigues Neto - Integrante / Irene Cristina Magnabosco Mocellin - Integrante / Luiz Eloi Vieira Jr. - Integrante / Carlos Renato Rambo - Integrante.
