Abstract:
A pure titanium part and a preparation method therefor. The method comprises: pre-oxidizing pure titanium powder; and performing additive manufacturing on the pre-oxidized pure titanium powder by using a high-energy beam, so as to form an oxygen atom solid solution strengthened pure titanium part. The pure titanium part machined on the basis of an additive manufacturing process has high degree of freedom and simple process. In addition, before the pure titanium powder is processed by using the high-energy beam, the pure titanium powder is pre-oxidized, so that sufficient and uniform oxide can be introduced, thereby improving the performance of the prepared pure titanium part.
