The Use of Metallography for Examination of Causes of Surface Defects on Visual Parts
Original language description
Many of currently manufactured components intended for automotive, must not only meet the requirements on functionality, but also considerable demands on the visual. Parts are subjected to thorough inspection and suppliers are forced to deal with causes of a very slight visual defects. When examining the defects, it is necessary to use a whole range of advanced analytical methods and procedures previously used only for identification of the physical and chemical properties and structure of the material. This paper deals with several cases which have been solved. It focuses especially on the use of demanding metallographic sample preparation from components with surface defects, examining the defects in the cut using mainly microscopic techniques and determining the causes of defects based on the results. These results then serve as a basis for corrections of production technology and thus are the tool for significant reduction of amount of NOK parts.
