Notes:
Under optimization deposition parameters, such as the acetone concentration, reactivepressure, the bias power, diamond films was deposited on cemented carbide tools with two-steppretreatment method under different distances between the substrates and hot filaments, and thestudy on the effect of the distance between the substrates and hot filaments on the crystallographicorientation of diamond films and the characteristics of diamond coated tools were investigated inbias-enhanced HFCVD system in this paper. The cutting performance of diamond coated tools wasverified by the experiments of cutting particles reinforced aluminum base composite material with15 vol.% Si as compared with uncoated ones. The quality of diamond film was analyzed by meansof SEM, Raman spectrum, and X-ray diffraction. The optimization deposition processing wasobtained. The relative intensity ratio of (111) facet and (220) facet in the film tested by XRD wasone third. The cutting performance of diamond coated tool was improved significantly whenmachining the Si particle reinforced aluminum-based metal matrix composite; its lifetime was as 30times long as that of uncoated one. The work of this paper was of great practical significance toaccelerate the industrialization of diamond films coated WC–Co substrates
