dc.description.abstract | Co-Cr-Mo (ASTM: F-75) alloy is
generally used because of their mechanical
properties, good wear and corrosion resistance
as well as biocompatibility. In order to obtain
chemical similarity and interfacial bond form
between implanted biomaterials and living
tissue, addition of Hydroxyapatite (HAP) is
required. This study has focused on a research
in F-75 alloy mixed with HAP fabricated by
powder metallurgy (P/M) technique. The effect
of HAP addition ranging 2 to 10 wt. % of HAP
on biocompatibility (corrosion resistance) was
examined. To analyse the result, the reference
sample (F-75 alloy without HAP) and
composites are compared. All samples are
immersed into 0.9% NaCl solution at 37 ûC in
6-week duration. Every interval of 48 hours, the
weight loss per area is recorded. By increasing
amount of HAP, it is noticed that corrosion rate
is increasing except for composite with 2 wt.%
of HAP which has the lowest corrosion rate
among others. The possibilities of increasing
corrosion rate are the formation of general
attack and pitting. Besides, the formation of
apatite layer can be seen as predicted. | en_US |
