Modified with permission from Sorrentino et al. (2019).. Proper bonding between the zirconia restoration and the tooth is important for the longevity of the prosthetic restoration (Araújo et al., 2018; Melo et al., 2015; Heboyan et al., 2023).Zirconia requires surface treatments with acid .
The tensile test results of the Ori-1 and Corr-1 spots are shown in Fig. 5. The yield strength (YS) and ultimate tensile strength (UTS) of Corr-1 were increased by 22.5%, compared to the initial Ori-1. Young's modulus was increased but the strain decreased by 50%. These values indicated that Zirconium alloy hardened after the corrosion process. The mechanical and cracking behaviour of a Cr coating, deposited on an Optimized ZIRLO T M substrate using the Cold Spraying (CS) technique, was investigated by in-situ scanning electron microscopy (SEM) tensile testing at room temperature. To achieve this, curved micro-tensile samples were machined from cladding tubes, and a styrene-assisted .
