Coating Hidroksiapatit Pada Logam Stainless Steel 316l Menggunakan Metode Dip Coating Dengan Variabel Temperatur Sintering Dan Komposisi Air Dalam Suspensi

---

Stainless Steel 316L is metal that can be used as a bone plate, but it has low biocompatibility. To achieve better biocompatibility with bone, Stainless Steel 316L can be coated with hydroxyapatite. Hydroxyapatite (HA) is the main inorganic phase of human bone with a composition around 65% of our bone. Dip coating techniques was used to apply hydroxyapatite into Stainless Steel 316L. Stainless Steel 316L with a size of 2x1x0,1 cm was dipped into a suspension containing HA, sago starch and water mixed with a rate of 250 rpm for 20 hours. Suspension were prepared with compositions 16 gram, 18 gram and 20 gram aquadest. And then coating HA were dried in oven at temperature 110 °C for 30 minutes. Coating HA were sintered at temperatures of 600°C, 700°C and 800 °C for 1 hour. SEM observation showed that the thickness of HA coating composition of 20 gram, 18 gram and 16 gram increased in the range of 42 – 144 μm. Meanwhile, the increment of sintering temperature did not influence the thickness of HA coating. The Coating thickness with sintering temperatures of 600°C, 700°C and 800 °C were in the range of 113 – 117 μm. XRD analyses showed that relative intensity of HA coating increased with increment of sintering temperature. Maximum shear strength obtained in this research was 11,78 MPa.
