Coating Trends For Fasteners
1999-12-01
1999-01-3072
Along those lines, General Motors do Brasil started to develop a protective coating that is corrosion resistant and environment friendly. At first, this will be used for fasteners. ...This study describes metallic and organometallic coatings with an increased resistance to corrosion associated to temperature, free of such harmful metals as cadmium, nickel, lead, chromium, etc. ...The friction coefficient is also related to the performance (efficiency) of the screw joint. The coating is completely recyclable, special consideration being given to reduced energy consumption, reduced metal waste and simplified waste handling during coating application to control proliferation and usage of toxic substances.

Types of lubricant treatments available for GA steels include further iron plating on top of it's surface1), a reaction type prephosphate treatment in which a preparatory fine phosphate coating is formed on the plating and a non-water rinse type prephosphate treatment in which phosphate treatment is conducted without the water rinsing stage.

Next Generation Catalysts are Turbulent:Development of Support and Coating
2004-03-08
2004-01-1488
Future catalyst systems need to be highly efficient in a limited packaging space. This normally leads to a design where the flow distribution, in front of the catalyst, is not perfectly uniform. Measurements on the flow test bench show that the implementation of perforated foils for the corrugated and flat foils has the capability to distribute the flow within the channels in the radial direction so that the maximum of the given catalyst surface is of use, even under very poor uniformity indices. Therefore a remarkable reduction in back pressure is measured. Emission results demonstrate cold start improvement due to reduced heat capacity. The use of LS - structured ( Longitudinal structured ) corrugated foils creates a high turbulence level within the single channels. The substrate lights-up earlier and the maximum conversion efficiency is reached more quickly.

Thermal Analysis and Experimental Investigations on the Effect of Thermal Barrier Coating on the Behavior of a Compression Ignition Engine Operated with Methyl Esters of Waste Cooking Oil

Next, combustion chamber parts like piston and cylinder head, inlet and exhaust valves were coated with Thermal Barrier Coating (TBC) and engine behaviour was studied. To make the study more interesting a thermal- stress analysis was done on the engine piston to examine the impact of coating on engine performance. ...To make the study more interesting a thermal- stress analysis was done on the engine piston to examine the impact of coating on engine performance. Results claimed that Brake Thermal Efficiency (BTE) of the engine operated with methyl esters of WCO showed marked improvement as compared to its neat form. ...Engine results with thermal barrier coating reported improved BTE as compared to the earlier case. Interestingly, all the carbon based emissions were drastically reduced at the cost of increased oxides of nitrogen emissions.
