How can we coat an implant surface in the lab and what characterisation techniques are used? Thanks.
Dear Hendra,
thanks for your advice. I think it can be good idea to compare dip coating with other techniques, such as plasma spray and electrospinning. Please advise, what kind of characterisation I can use after coating. Best regards
plasma spray can be used to coat the implant surface. The ceramic and alloy coatings can be fabricated on the implant. The main characterisation techniques are SEM and XRD. The cross-scection of the as- prepared coatings must be prepared and it is difficult.
many thanks as I am getting my concepts clear. regarding plasma spraying, what kind of parameter you recommend for coating implant surface with polymers or ceramics? regards
Dear zafar
mechanical properties of sprayed coating should be taken into account, because in plasma spray process the usual defect such as voids and micro-crack are undeniable. Also, Adhesive strength is so important.
the plasma spray parameters such as spray distance, power and so on can influence on mechanical and physical properties of coating.
how can we check the adhesive strength of the coating? scratch test wil be OK or any other, thanks
scratch test is one of the way , but in my idea best way is tensile test
Amir: please send me the standards for both, it will be of great help
Dear Amir, many thanks, Sorry I had limited internet access. I got it. I will be in touch with you. Keep in touch. thanks
