Mevcut çalışmada, ticari saf titanyum numuneler biyouyumluluk açısından önem arz eden yüzey
pürüzlülüğünün sıvı temas açısı üzerine etkisini incelemek için değişik asit ve alkali çözeltilerine maruz
bırakılmıştır. Bu amaçla, titanyum yüzeyi 6 farklı asit ve alkali çözeltileri ile uzun süreli dağlanmıştır.
Yüzeyler mekanik profilometre, sıvı temas açısı ölçüm cihazı ve taramalı elektron mikroskobu (SEM) ile
incelenmiştir. Çalışma sonucunda, titanyum implant yüzeyindeki pürüzlülük değerinin artışı ile sıvı
temas açısının arttığı görülmüştür. Orijinal numune ile mukayese edildiğinde, 1K, 2K ve 3K kodlu
numunelerde yüzey pürüzlülüğü ve sıvı temas açısı düşmüş, 4K, 5K ve 6K kodlu numunelerde ise artma
eğilimi göstermiştir. Bu durum ilk 3 kimyasal işlemin titanyum yüzeyinde hidrofilik bir özellik
oluşturduğunun göstergesidir.
