Abstract

The paper deals with the experimental study of laser beam micromachining of the powder metallurgy processed Ti compacts applying the industrial grade fibre nanosecond laser operating at the wavelength of 1064 nm. The influence of the laser energy density on the surface roughness, surface morphology and surface elements composition was investigated and evaluated by means of surface roughness measurement, scanning electron microscopy (SEM), energy dispersive X-Ray spectroscopy (EDS) and X-ray diffraction (XRD) analysis. The different laser treatment parameters resulted in the surfaces of very different characteristics of the newly developed biocompatible material prepared by advanced low temperature technology of hydride dehydride (HDH) titanium powder compactation. The results indicate that the laser pulse energy has remarkable effects on the machined surface characteristics which are discussed from the point of view of application in dental implantology.

摘要

本文论述了采用工作波长为1064nm的工业级光纤纳秒激光对粉末冶金处理的钛坯块进行激光束微加工的实验研究。通过表面粗糙度测量、扫描电子显微镜（SEM）、能量色散X射线光谱（EDS）和X射线衍射（XRD）分析，研究并评估了激光能量密度对表面粗糙度、表面形貌和表面元素组成的影响。不同的激光处理参数导致了采用先进的低温氢化脱氢（HDH）钛粉压实技术制备的新型生物相容性材料表面具有截然不同的特性。结果表明，激光脉冲能量对加工表面特性有显著影响，并从牙种植学应用的角度进行了讨论。
