Argon plasma treatment techniques on steel and effects on diamond-like carbon structure and delamination

“…The pretreatment process at 600V also results in additional topographical features related to substrate boundaries, which are likely to be detrimental in some applications. The alterations in the film structure are likely to have an effect on the applicability of the films across sectors [4][5][6][7][8][9][10] and suggest that in addition to deposition phase processes, the parameters of the pretreatment process need to be considered when designing diamondlike carbon coatings. Table 2.…”

“…Tuning the balance of the constituents, phases and ordering allows the creation of an amorphous carbon material with properties that can range from polymer-like to diamond-like. This range of materials can therefore be tailored to match functional requirements, resulting in applications in many areas including aerospace [5] manufacturing [6] and medical devices [7][8][9][10].…”

“…These layered structures have improved adhesion on substrates including stainless and high-speed steels [6,7,19] silicon [7,17] and Ti-Al-V alloys [18]. Other research teams have used thick interlayers such as ceramic or epoxy [5]. Many groups [5,6,13,[19][20][21][22] also utilise an argon plasma pretreatment process, and this has been shown to be important in film adhesion [5,20,21].…”

Many groups [5,6,13,[19][20][21][22] also utilise an argon plasma pretreatment process, and this has been shown to be important in film adhesion [5,20,21]. However, parameters for this process vary substantially between groups; duration can vary from 5min to 1 hr and bias voltage from 300V to 700V.…”

The Wear Resistance of Cr-C-Al2O3Composite Deposits Prepared on a Cu Substrate using Cr3+-based Plating Baths

“…This directive restricts the use of six toxic substances, including Cr +6 ions, in the manufacturing process for electrical and electronic products. Therefore, the development of alternative coatings has become an important topic in recent years [2,3]. Trivalent Cr electroplating, among all of the alternative options, is considered to have a great potential in replacing conventional hexavalent Cr electroplating for its relatively low toxicity and high current efficiency [4][5][6].…”
