Influence of humidity on the friction of diamond and diamond-like carbon materials
The friction of diamond and diamond-like carbon (DLC) materials was evaluated in reciprocating sliding wear testing under controlled relative humidity. The testing conditions were a displacement stroke of 100 mm, an oscillatory frequency of 8Hz and a normal load of 2N. The coefficient of friction of diamond and hydrogen-free DLC (a-C) coatings against a corundum sphere in the steady regime decr...
متن کاملLow temperature internal friction of diamond-like carbon films
We have studied the internal friction of amorphous diamond-like carbon films prepared by pulsed-laser deposition from 0.4 to 300K. The low temperature internal friction below 10K is dominated by the atomic tunnelling states for amorphous solids, which is a measure of structure disorder. We have tried to vary the content of sp carbon atoms versus sp ones by changing laser fleunce, by doping with...
متن کاملTesting of Diamond-Like Carbon Coatings under Slip-Rolling Friction Monitored by Acoustic Emission
Wear tests were carried out on different DLC coatings under lubricated and dry slip-rolling friction in a Twin-Disc Testing rig. The analysis of Acoustic Emission (AE) provided an easy and comfortable tool for monitoring the wear life of DLC coatings. A DLC coating in-service was indicated by the appearance of no or just single AE events due to single damages (crack, small spallings, etc.) to t...
متن کاملthe influence of the neo-platonic concept of poetic imagination on wordsworth’s poetry
بر اساس نظریه افلاطون در باره شعر خلاقیت هنری مورد انتقاد قرار گرفته است. نظریه کلی در مورد شعر این بود که شعر از ظواهرتقلید میکند و نه حقیقت. چون سایه ای از حقیقت است. اما با پیدایش فلسفه نو افلاطونی، انتقاتات قبلی در مورد شعر و شاعری اصلاح شد. فلوطین در کتاب انئید، اساس خلق هنری را بر محور مُثل افلاطونی قرار داد. وی باور داشت که هنر مندان در خلق آثار هنری، تحت تاثیر مُثل افلاطونی بوده و عوالمی ...
