The surface of machine elements is changed to improve their mechanical properties. Ceramic-metal composite coatings are mainly used increase the durability parts. Therefore, new materials constantly searched for application in future development metal and ceramic composites. nickel iron usually as a base Al2O3 tough particles. welding technology applying alloy widely used. common apply thermal ...

The relationship between the quality of finishing works, costs, market value, and profit, is presented and explained for residential buildings. The results show that the higher quality of finishing works increases profit for investors. As the maximum market price is limited, there is a limit when the investment in finishing work is no longer cost-effective as, after increase in costs, the marke...

Quick Facts... •Meeting protein, energy, vitamin and mineral requirements is essential for profitable lamb finishing. •Feedlot lambs are more efficient when self-fed than when hand-fed twice daily. •Lambs fed whole grains have as good or better performance than when they are fed rolled or ground grains. •If lamb finishing rations are more than 60 percent roughage, they should be pelleted for be...

Rate and efficiency of gain were not affected by adding as much as 20% distillers dried grains in isocaloric diets for nursery pigs or 30% in isocaloric diets for finishing pigs. These results demonstrate that the previously suggested maximums of 5% distillers dried grains in nursery diets and 10% distillers dried grains in finishing diets are too conservative. Finally, because the 20% (nursery...

In this paper, a new non-contact ultrasonic abrasive finishing mechanism is designed and fabricated. This mechanism combines the function of ultrasonic vibrations and the magnetic abrasive finishing (MAF) process. A permanent magnet which is mounted on a horn has been used as the processing tool. This polishing tool is vibrated at an ultrasonic frequency with piezo-electric actuators. Ultrasoni...
