AISI 316L paslanmaz çelik (SS), implant ve biyomalzeme üretiminde en yaygın kullanılan metalik biyomalzemelerden biridir. Muadil biyomateryallerle kıyaslandığında düşük maliyet, iyi mekanik özellik ve biyouyumluluk gibi avantajları mevcuttur. Gözenekli biyomalzemelerde bulunan gözenekler mekanik bir kenetlenme sağlayarak implantın dokuya güçlü bir şekilde tutunmasını sağlar. Bu çalışmada gözenekli SS implant elde etmek için 316L alaşım tozu içerisine hacimce %20, %30 ve %40 oranında polivinil alkol (PVA) ve Bor ilave edildi. Paslanmaz çelik implant malzemesi üzerinde gözeneklilik ve bor etkisinin araştırılması amacıyla PVA ve Bor katkılı gruplarda üretilen numuneler, 1180 ᵒC' de argon atmosferi altında sinterlenmiştir. Yapıdaki PVA' nın buharlaştırılmasıyla iki grup halinde gözenekli ve bor katkılı numuneler elde edildi. Son olarak numuneler Brinell sertlik ve basma testlerine tabi tutularak SEM, EDS ve XRD analizleri yapıldı. Sertlik testleri sonucunda en yüksek değerler 37.006, 31.32, 25.28 HB olarak ölçülmüştür. Basma dayanımı ise %20, %30 ve %40 gözenekli numuneler için sırasıyla 39.5, 34.5, 26.2 MPa olarak ölçülmüştür.

Effects of Porosity and Boron Reinforcement in AISI 316L Stainless Steel for Biomedical Applications

Öz

AISI 316L stainless steel (SS) is one of the most widely used biomaterials in the manufacture of implants and biomaterials. It has advantages over equivalent biomaterials such as low cost, good mechanical properties and biocompatibility. The pores found in porous biomaterials provide mechanical interlock, ensuring strong attachment of the implant to the tissue. In this study, 20%, 30% and 40% by volume of polyvinyl alcohol (PVA) and Boron powder were added into 316L powder to obtain porous SS implant. To investigate the effect of porosity and boron effect on the stainless-steel implant material, the samples produced in PVA and Boron added groups, were sintered at 1180 oC under an argon atmosphere. With the evaporation of PVA in the structure, porous and boron added samples were obtained in two groups. Finally, the samples were subjected to Brinell hardness and compression tests and analyzed by SEM, EDS and XRD. As a result of the hardness tests, the highest values were measured as 37.006, 31.32, 25.28 HB. 39.5, 34.5, 26.2 MPa strengths were measured for 20%, 30% and 40% porous samples respectively.
