Abstract
QQC, Inc. has developed a revolutionary diamond deposition technique w hich does not require a vacuum, or H-2, or ''chemical'' or physical pr e-treatment of surfaces. The process utilizes a combination of various pulsed lasers and is performed at the laboratory p-t conditions: with CO2 and N-2 as shrouding gases. Crystalline diamond films and DLC or, more accurately, tetrahedral non-crystalline carbon (TNC) have been f ormed on various substrates. On WC cutting tools the rate of depositio n of crystalline diamond is approximately 1 mu m/sec. In the context o f fabricating a diamond coating on a substrate, the entire pre-surface treatment and material synthesis process including a coating regime, is performed in one step.
