Medical implants and other biomaterials are used by millions of individuals all over the globe to restore lost bodily functions due to injury or illness. Many of these implants fail after a short time or have difficulties, despite the fact that they play important roles in keeping a person's life safe or increasing the quality of their lives. It is the lack of biocompatibility that has proven to be the biggest downfall of biomaterials. Investments in this industry may be made using a thin film of hydroxyapatite powder (HAP) on stainless steel. Plates, screws, pins, and artificial joints are only some fixation devices for bones that often use 316L stainless steel. However, due to its unique advan­tageous qualities such as super-elasticity and low-profile feature, thin film HAP signals a high potential for use in compact new cardiac devices like the cardiovascular system and protecting stent grafts.

Recently, magnesium alloys have garnered a lot of interest as a potentially useful material for applications involving biodegradable implants. Cracking or fracture of metal-based implants under the combined action of corrosion and mechanical stresses, namely stress corrosion cracking (SCC) is an obviously critical criterion before any new material might be deployed as implants. Cracking or fracture of metal-based implants occurs under the simultaneous action of corrosion and mechanical stresses. This article gives a review of the existing literature on the SCC of magnesium alloys in corrosive environments, including simulated body fluid and the accompanying fracture process. It also indicates the knowledge gap that exists in this area of research. In addition, a high-level review of the preventative measures that may be taken to avoid potential corrosion fatigue failures in magnesium alloys is provided.
