This paper presents a comparative analysis of process performance of micro-grinding and electrochemical honing, with the aim to achieve higher precision and surface quality of rebuild surfaces of the engine valve face. The discarded engine valve face was rebuilt using plasma transferred arc...

Determination of optimal input parameters is one of the important elements in any process planning of the metal parts. The aim of the study is to investigate the optimization of processing parameters in order to enhance the surface micro-finish and geometrical accuracy of the recovered...

With the fast development and frequent changes of the engineering products, natural resources are arbitrary exploited and the environment is used without repayment, which causes many problems of great magnitude such as zoology damaged all over the globe, resource waste and depletion,...
