Abstract The effect of high frequency pulse detonation (HFPD) and HVOF thermally sprayed WC-Co coatings on the high cycle fatigue (HCF) behavior of 2024-T4 aluminum was investigated. The fatigue life distributions of specimens in the polished and coated conditions are presented as a function of the probability of failure. The monotonic and cyclic deformation behaviors of the as-received and as-coated specimens were investigated. The conclusions show that, (i) the HFPD sprayed specimens exhibited slightly higher fatigue lives compared to the uncoated specimens, (ii) the HVOF sprayed specimens exhibited significantly higher fatigue lives compared to the uncoated specimens, and (iii) the as-coated specimen was cyclically stable.

signals, namely the measurement of the partial dis-charge pulse current. The Roche coil works in mag-netic coupling, and the detecting circuit and the high-voltage circuit has no direct contact, so it is very suitable for the partial discharge site inspection in the high-voltage switchgear. 3 APPLICATION OF HIGH-FREQUENCY PULSE CURRENT SENSOR IN THE WAIST STATION FOR 35 KV SWITCH CABINET A 220 KV waist station is located on a hill, which is far from about 2 km to the north of Yang street , 4 DATA DETECTION AND ANALYSIS OF Lufeng town, Lufeng country of Chuxiong city , alti-SWITCHGEAR HIGH FREQUENCY FOR tude 1923 km, which covers an area of 22876 m PARTIAL DISCHARGE and put into production on December 25, 2009. It is one of the most important substation of Chuxiong During the 2-month testing for the Chuxiong waist Lufeng area. The main power source is supplied by station , we selected the data from April 23 to May 220 KV and 500 KV peace waist I changed back 25 in 2014 for effective analysis, and found that the line, 220 kV and waist II loop power. current data of the eight high-frequency pulse cur-rent sensor is normal, so we selected three sensor

Formation of nanostructure states on the surface of materials exposed to concentrated flows of energy is one of the relevant problems of modern materials processing. In the paper the authors describe the mechanism of the micro-scale droplets formation based on the study and modeling of the physical processes and technological aspects of the interaction between the heterogenic plasma flows and the molten substance at the electrode tip. The authors show new physical mechanisms and criteria for micro-and nanoparticles origination, develop a physical-mathematical model of the interaction between the molten metal and the plasma discharge with imposed high-frequency pulse action.
