Coating stress
WebAs a result of the SSRT, the aluminum coating process decreased significantly the stress corrosion indexes of AZ31, AZ61, and AZ91 Mg alloys. The fracture of surface images was also examined in the SEM, and both intergranular and transgranular stress corrosion cracking were observed in all three alloys. Open Research DATA AVAILABILITY … WebMany modern-day optical coating technologies, such as magnetron sputtering and ion beam sputtering, involve high-energy material deposition. While these techniques …
