Laser Assisted Doping of Silicon Carbide Thin Films Grown
Cubic silicon carbide (3C-SiC) films were grown by pulsed laser deposition (PLD) on magnesium oxide [MgO (100)] substrates at a substrate temperature of 800°C. Besides, p-type SiC was prepared by laser assisted doping of Al in the PLD grown intrinsic SiC film. The SiC phases, in the grown thin films, were confirmed by x-ray diffraction (XRD

The friction and wear tester (CFT-I, China) (Fig. 2 (a)) was used to test the friction coefficient and wear rate through reciproing friction (Fig. 2 (b)) for 120 min in lubriing oil (N32) at room temperature under the load of 3 N [, , ].The sliding speed was 300 rpm and the stroke length was 5 mm. The counterpart was a steel ball (45 #) with the diameter of 10 mm (Fig. 2 (c)).
Silicon Carbide Thin Films using 1,3-Disilabutane Single
Silicon carbide thin films have been deposited with CVD using two precursors, one for Si and one for C. Various chemistries have been implemented, including silane or dichlorosilane for the Si source and propane or acetylene for the carbon source (4-8). Single-source precursors containing both Si and C in the same molecule including

Silicon Carbide Films Prepared by Silicon Nitride
Silicon carbide (SiC) films were synthesized on graphite substrates using silicon nitride (Si 3 N 4 ) as silicon source at 1850°C, 1950°C, 2050°C and 2150°C, respectively. The characteristics of the synthesized films were analyzed by X-ray diffraction and scanning electron microscopy. The results show that the synthesis reaction can take place above 1850°C, and the SiC films were β-SiC.
Silicon Carbide or Aluminiun Oxide?? - Tools and Tool
Feb 05, 2010· Silicon carbide is a harder abrasive, but aluminum oxide is plenty hard for steel. Either will work. The biggest differences in stones are how they cut, which is a funtion of the abrasive and the binder used to "glue" the abrasive particles together. There is no way to know until you try them, sadly.

The Ins And Outs Of Silicon Carbide
Fig. 1: SiC MOSFET. Source: Cree. SE: How about with SiC? Palmour: Silicon carbide has a 10 times higher breakdown field.Our 600-volt MOSFET is going to be as fast as a 60-volt silicon MOSFET. The other way to look at it is if you say 600 volts is the voltage at which you switch from MOSFETs and silicon over to IGBTs, we would be at 10 times higher voltage.
Hydrogenated Silicon Carbide Thin Films Prepared with High
Structural, optical, and electrical properties of hydrogenated silicon carbide (SiC:H) films, deposited from silane (SiH 4 ) and methane (CH 4 ) gas mixture by HW-CVD method, were investigated. Film properties are carefully and systematically studied as function of deposition pressure which is varied between 200 mTorr and 500 mTorr.

Characterization of Silicon Carbide Films Prepared by
Silicon carbide prepared by chemical vapor deposition (CVD) is one of the important candidate materials for space mirror and high-power mirror such as laser mirror, because of its superior performances such as low density, high melting point and homogeneity. In this paper, the SiC coatings were deposited on the substrates of reaction bonded silicon carbide (RB-SiC) by CVD process.

The material may be a metal such as brass, aluminum, copper or steel or it can be a semiconductor such as silicon carbide,carbon or graphite. To heat non-conductive materials such as plastics or glass, induction is used to heat an electrically-conductive susceptor, typically graphite, which then transfers the heat to the non-conducting material.
