Abstract:
Die vorliegende Erfindung betrifft eine verschleißfeste Kette mit jeweils mittels eines Kettengelenks (4, 23) miteinander verbundenen Kettengliedern (2, 3, 13, 14). Zumindest ein einem Reibverschleiß ausgesetzter Oberflächenbereich (24, 18, 19) der Kettengelenke und/oder der Kettenglieder ist mit einer Verschleißschutzbeschichtung (25, 26, 27) mit zumindest zum Teil nanokristalliner Struktur versehen. Das bedeutet insbesondere, dass Hartstoffpartikel in Nanogröße in einer Matrix dispergiert sind.
Abstract:
A method of controlling defects in boron nitride films in order to stabilize certain crystallographic structures is disclosed. Such defects include, for example, nitrogen vacancies, boron interstitials, and substitutional dopants. In particular, films produced by the method of sputtering in pure inert gas atmospheres have a tetrahedrally coordinated structure and are rich in nitrogen vacancies. Films produced by the same method in inert gas with a sufficient nitrogen overpressure have a completely stoichiometric graphitic structure. These results are expected for any defect type having a greater free energy of formation in the graphitic form of boron nitride than in the tetrahedral forms. The methods of the invention are applicable to any film growth technique capable of incorporating such defects.

Abstract:
The invention provides an arc coating apparatus having a steering magnetic field source comprising steering conductors (62, 64, 66, 68) disposed along the short sides (32c, 32d) of a rectangular target (32) behind the target, and a magnetic focusing system disposed along the long sides (32a, 32b) of the target (32) in front of the target which confines the flow of plasma between magnetic fields generated on opposite long sides (32a, 32b) of the target (32). The plasma focusing system can be used to deflect the plasma flow off of the working axis of the cathode. Each steering conductor (62, 64, 66, 68) can be controlled independently. In a further embodiment, electrically independent steering conductors (62, 64, 66, 68) are disposed along opposite long sides (32a, 32b) of the cathode plate (32), and by selectively varying a current through one conductor, the path of the arc spot shifts to widen the erosion corridor. The invention also provides a plurality of internal anodes, and optionally a surrounding anode for deflecting the plasma flow.
