to the deposition process, the WC-Co inserts were pretreated by a two-step chemical etching method. Firstly, the WC-Co inserts were dipped in the Murakami’s reagent of 10 g K3Fe(CN)6 + 10 g KOH + 100... filament chemical vapor deposition (HFCVD) diamond films are significantly influenced by the deposition parameters, such as the substrate temperature, total pressure and carbon concentration......
