Purpose: The paper presents the comparison of selected properties of surface layer between samples produced from Ti6Al4V titanium alloy by using injection casting with two options: injection with suction, injection without suction. Design/methodology/approach: Produced elements have been made of Ti6Al4V titanium alloy. The aim of the study was to compare selected properties of the surface layer of produced elements. The paper compares microstructure, microhardness and surface geometry after injection casting with and without suction. Additionally, all mentioned studies were carried out for input material. Findings: Research has shown that the use of innovative injection methods with and without suction for production of elements from Ti6Al4V titanium alloy affects on their structure and thus examined properties. It was observed that the elements produced by injection casting method have higher hardness values and lower development of surface,where sample produced by injection casting with suction has higher value of hardness and lower development of surface than sample produced by injection casting without suction. During the observation, a sample with suction has higher amount of a phase in cross-section surface layer than a sample without suction what can be caused because of the higher speed of heat transfer from produced element to the internal surface of the copper mould. Research limitations/implications: There can be a problem to make final elements with a more developed surface. Practical implications: Injection casting with suction can be used to produce small elements with different geometry from Ti6Al4V titanium alloy. Originality/value: The paper presents the possibility to improve selected properties of element surface produced by injection casting with suction and without suction.
