We demonstrate an environmentally friendly and scalable method to create fluorine-doped diamond-like carbon (F-DLC) coatings using plasma immersion ion implantation plasma-enhanced chemical vapor deposition (PIII-PECVD) with 1,1,1,2-tetrafluoroethane. F-DLC films tend have low wettability good mechanical flexibility, which make them suitable for applications in biomedical devices antibiofouling surfaces. report on the effects of fluorine incorporation surface chemistry, energy, morphology...
Abstract Silicon oxide‐containing diamond‐like carbon (a‐C:H:Si:O) films are a promising class of protective coatings for environmentally‐demanding applications owing to their lower residual stresses and superior thermal stability oxidation resistance relative undoped carbon. However, existing versions a‐C:H:Si:O deposited by traditional methods such as plasma‐enhanced chemical vapor deposition (PECVD) undergo substantial degradation at temperatures above 250 °C. This, together with the...
The objective of this work is to compare the performance uncoated micro end mills with coated using various pretreatments and diamond coatings. Testing conducted 300-um-diameter, two-flute, carbide cutting full-width slots in 6061-T6 aluminum. comparison these tools a robustness test where feed rate tool increased every 5 mm linear travel until catastrophic failure occurs. outcomes from tests are maximum chipload, therefore material removal rate, force experienced by tool. It has been...
Red phosphorus, when exposed to humid environments in air, breaks down into toxic phosphine gas and acidic phosphorus species, presenting a challenge for many applications, such as flame retardants or pyrotechnic obscurants. We have developed characterized method of plasma-deposited carbon form nanometer-thick, chemically stable layer on red particles suppress production. Using combination XPS surface analysis novel IR headspace method, we quantified an understanding the reaction with water...
