| Summary: | <p>Surface roughness and wettability determines the rate and quality of protein adsorption and cells<br />
adhesion on biomaterial. A rough- and hydrophilic-surface are better for adsorption of specific<br />
proteins and promotion of the following biological processes than a smooth- and hydrophobicone.<br />
This paper discusses the effect of surface mechanical attrition treatment (SMAT) on the<br />
roughness andwettability of AIS1316L. The polished samples were treatedfor 0 - 20 minutes. The<br />
result shOtt'sthat SMA Tprocess enhances surface roughness and decreases droplet contact-angle.<br />
Increasing of SMAT duration enhances microhardness of the sample's surface and subsurface,<br />
and yields a relatively smooth surface that reduces hydrophilicity of A/SI316L.</p> |
