The Leeb hardness tester is a kind of test equipment. The principle is based on the development of the monolithic technology in 1978, Dr. Leeb of Switzerland proposed a new method of hard testing for the first time. Its basic principle effects body with a high quality. Impacting the surface of the s

what is the use of ultrasond sensorResearches on the microstructure of plasma sprayed BaTiO3 coatings have recently made new progress. The microstructures of BaTiO3 coatings, the cross-sections of plasma BaTiO3 coatings and the microstructures under plasma spark plasma sintering can be seen. Part of
