Plasma surface engineering in the automotive industry—trends and future prospectives

Tribological Properties of Fluorinated Amorphous Carbon Thin Films

“…These properties can be tuned by modifying DLC structure and by incorporating other elements [Hauert & Patscheider, 2000], whereas other properties ensure its performance as optical filter or for components with electronic functionality. The fastest growing market for DLC application during the previous years was the automotive industry [Lampe et al, 2003], in which DLC, ta-C, W-DLC and WC/C multilayers were being preferentially developed as hard and tribological coatings [Hauert, 2004]. Automotive industry demands solutions for preparing low friction and wear resistant coatings for lubricant performance on components.…”

Surface technology for automotive engineering

“…It is noteworthy that besides coating processes also other surface treatments like nitriding, especially plasma nitriding, can considerably improve the performance of automobile components [113]. The potential of plasma nitriding will be considered more detailed below.…”

“…Cylinder bores of aluminium cast engine blocks-coatings consisting of carbon steel partly reinforced by ceramic particles, prepared by thermal spraying [6,113,17]. Older variants of such coatings are nickel based composites or hard chrome [117].…”

Morfologia da camada nitrocarbonetada a plasma do aço DIN 100Cr6

“…A obtenção de propriedades como ótima resistência mecânica, grande estabilidade química e boas propriedades magnéticas motivou nos últimos anos intensas pesquisas nesta área dos tratamentos termoquímicos. Já existem atualmente inúmeras aplicações para estes materiais, principalmente ligadas às indústrias do setor metal-mecânico (3) , tais como a fabricação de motores automotivos mais leves e duráveis (4,5) e a utilização de ferramentas mecânicas com maior resistência e maior durabilidade.…”
