Abstract Scope |
SLM is an additive manufacturing method for producing dental crown and bridges (DCB) using CoCrMo alloy powders. The powder composition plays a crucial role in the mechanical and chemical bonding of metal and ceramic materials. This study investigates the effect of minor and trace percentage in the composition on CoCrMo powder alloys. Three CoCrMo alloy powders that have different minor and trace component weight percentages have been analyzed. Density and microstructural analysis were carried out to determine the optimal SLM process parameters and heat treatment for bulk specimens. Tensile, corrosion and de-bonding crack initiation tests were performed on the samples. Results show that slight differences in chemical composition can impact the mechanical and corrosion responses, highlighting the importance of carefully selecting the powder composition for successful SLM manufacturing of dental parts. |
