“…However, there are still problems for plasma spraying, for example, due to the high temperature of spraying, the HA coating would produce an amorphous phase after spraying, which might affect the interface integrity of the bone implant. Strong reabsorption of the amorphous phase may cause mechanical and bonding instability of the coating, which limits its application [ 22 ].…”

The wide application of magnesium alloys as biodegradable implant materials is limited because of their fast degradation rate. Hydroxyapatite (HA) coating can reduce the degradation rate of Mg alloys and improve the biological activity of Mg alloys, and has the ability of bone induction and bone conduction. The preparation of HA coating on the surface of degradable Mg alloys can improve the existing problems, to a certain extent. This paper reviewed different preparation methods of HA coatings on biodegradable Mg alloys, and their effects on magnesium alloys’ degradation, biocompatibility, and osteogenic properties. However, no coating prepared can meet the above requirements. There was a lack of systematic research on the degradation of coating samples in vivo, and the osteogenic performance. Therefore, future research can focus on combining existing coating preparation technology and complementary advantages to develop new coating preparation techniques, to obtain more balanced coatings. Second, further study on the metabolic mechanism of HA-coated Mg alloys in vivo can help to predict its degradation behavior, and finally achieve controllable degradation, and further promote the study of the osteogenic effect of HA-coated Mg alloys in vivo.

“…İmplant yüzeyinin kemik minerali ile kimyasal olarak benzerlik gösteren ve kemik doku oluşumunu tetikleyici bir biyoseramik olan hidroksiapatit ile kaplanması veya yüzeyde biyoaktif apatit oluşumunu tetikleyici işlemler uygulanması da osseointegrasyonun artırılması amacıyla implant yüzeylerine yaygın olarak uygulanan yöntemler arasındadır [29][30][31][32][33][34]. Yüzeye hidroksiapatit tabakası kaplanması amacıyla kimyasal daldırma işlemleri, plazma sprey kaplama veya püskürtme gibi yöntemler kullanılmaktadır [29][30][31][32]. Sentetik vücut sıvıları içinde statik daldırma ile biyomimetik kaplama yöntemi ise, yüzeyde apatit oluşumunun tetiklenmesi ile biyoaktivitenin artırılması amacıyla uygulanan, osseointegrasyonun iyileştirilmesinde önemli rol oynayan bir diğer yöntemdir [33,34].…”

The bond strength is a critical consideration for the plasma-sprayed NiCrBSi coatings. However, the conventional methods for testing the bond strength of NiCrBSi coatings always cost time and money. If there is a simple method that could predict the bond strength of the prepared NiCrBSi coatings without destroying the coatings, it would be significantly beneficial for industrial applications. In this work, a new method was proposed based on the total areas of the interfacial pores for the NiCrBSi coatings. The NiCrBSi coating was prepared by plasma spraying technology and the as-sprayed coating was subsequently remelted by plasma arc using the powers of 20 kW, 25 kW, and 30 kW, respectively. The interfacial microstructures, the size distributions and total areas of the interfacial pores, interfacial hardness, and bond strength of all prepared coating samples were investigated. After remelting, the number and the total area of interfacial pores decrease with increasing the remelting power. Correspondingly, the interfacial hardness and bond strength of coatings increase with increasing the remelting power The bond strength of coatings basically has a linear relationship with the total area of interfacial pores. The built relationship may be used to predict the bond strength of NiCrBSi coatings.
