The conventional grinding process has been the focus of several works dealing with Tasquinimod variety of materials such as ferrous and non-ferrous alloys, superalloys as well as ceramics [6], [7], [8] and [9]. These previous works have essentially focused on the chip formation [10], the modelling of the stresses and temperature fields [11], the evaluation of the temperature at the tool/material interface and within the material [12] and [13] and on the microgeometry and topography of the machined surface in conjunction with the variation of some grinding wheel characteristics [14]. These investigations were essential to better understand the grinding process and to improve its effectiveness. However, little information has been reported in the literature concerning the characterization of the deformed electrodeposited chromium coating after grinding. Thus, the consequences of grinding process on the coating integrity are still rather poorly understood. Eliaz et al. [15] have reported pre-cracking of the steel substrate induced by an improper choice of the grinding parameters of chromium coated parts which exposed the steel to local overheating during grinding. Other work has dealt with the influence of grinding parameters on fatigue resistance of chromium coatings concluding somatic cell the grinding finishing process could be a deteriorating factor in terms of fatigue resistance [16].
