Temperature Dependence of the Crystal Growth of Diamonds Deposited on Stainless Steel Substrates by the Combustion Flame Method

摘要

In order to obtain some useful information for the high rate combustion flame diamond deposition process using various substrates, as a basic study, diamond depositions on surface cooled stainless steels with varying acetylene/ oxygen flow ratios during operation and with twin gas torches were carried out. As a result, it was proved that the diamond deposition rate was promoted by varying the gas flow ratio and/ or using the twin gas welding torch.
