3.2.1. Evolution of residual stresses and crystallographic texture within the coating
The value of the surface residual stresses at the surface of all samples (i.e. before and after grinding of the electrodeposited coating using different grinding conditions) Trametinib gathered in Table 3. The σ11 (along the grinding direction) and σ22 (in the transverse one) stresses components are given while the other terms of the stress tensors are always small whatever the grinding condition.

As a first result, atom is observed that grinding drastically changes the value and the surface stress state. For sample Gw, stress is compressive in nature (σ11 = − 100 MPa) in the grinding direction while it is tensile in the transverse one (σ22 = + 200 MPa). In a similar manner, the Gd sample is characterized by a compressive stress in the grinding direction (σ11 = − 80 MPa) and a tensile one in the transverse direction (σ22 = + 280 MPa). It is interesting to note that both samples of the gentle conditions present rather close magnitude of the recorded compressive and tensile stresses.
