Penelitian bertujuan menentukan breakdown voltage karburasi plasma dan pemanfaatannya untuk meningkatkan kekerasan stainless steel 316L. Proses penentuan breakdown voltage karburasi plasma dilakukan dengan menggunakan gas CH4 dengan variasi tekanan 1; 1,2; 1,4; 1,6; 1,8; 2 mbar. Selain itu juga dilakukan proses surface treatment menggunakan gas CH4 dengan teknik karburasi plasma pada stainless steel 316L untuk meningkatkan kekerasan dengan variasi tekanan 1,2; 1,4; 1,6; 1,8 mbar. Breakdown voltage yang diperoleh dari perlakuan variasi tekanan berturut-turut sebesar 512; 540 ; 572,3; 602; 654,3; dan 655,7 volt, sedangkan nilai arus yang diperoleh berturut-turut 256; 457; 547; 708,3; 947,7; 986,7 mA. Hasil uji kekerasan menunjukkan nilai kekerasan optimum terjadi pada variasi tekanan 1,6 mbar dengan nilai kekerasan meningkat dari 109,4 VHN menjadi 228,6 VHN, atau meningkat sebanyak 108,88%.

Gel Method

In this research, bioglass nanoparticles were synthesized via sol-gel method and a polycaprolactone-chitosan-bioglass nanocomposite coating was formed on SS316L substrate using electrophoretic deposition method. Then, the effects of voltage and deposition time on morphology, thickness, roughness, and wettability of final coating were investigated. Finally, biocompatibility and toxicity of the coating were evaluated. The results showed that increase of both time and voltage enhanced the thickness, roughness, and wettability of coating. Also, increase of deposition time increased the agglomeration. Therefore, it can be concluded that voltage of 20 V and time of 10 min are suitable for the formation of a uniform agglomerate-free coating. The presence of bioglass nanoparticles also led to the increase of roughness and improvement of polycaprolactone hydrophobicity. The results also showed higher bioactivity in polycaprolactone-chitosan-1% bioglass nanocomposite coating sample. This sample had a roughness ( Ra) of 1.048 ± 0.037 μm and thickness of 2.54 ± 0.14 μm. In summary, the results indicated that coating of polycaprolactone-chitosan-bioglass nanocomposite on SS316L substrate could be a suitable surface treatment to increase its in vivo bioactivity and biocompatibility.
