In this study, the effect of deposition regime on the wear behavior of VK8 coating applied to 1.2344 tool steel by electro spark method (ESA) was investigated. After sample preparation, the coating with high and low regime was applied. To assess the wear behavior, the pin on disk test method according to ASTM G99-04, was used. For surveying surface morphology and cross section of the coating as...

The aim was to study the effects of technological residual stresses on bending stiffness cylindrical parts shafts and axes. Experiments were conducted for elongated specimens made steel grade 35 with a diameter 30 mm using boring turning methods. Specimens annealed in protective medium remove initial stresses. carried out an Amsler laboratory hydraulic testing machine VK8 hard-alloy matrices. e...

This paper compares stresses arising in the tool material of combined end-milling cutters and their admissible values with purpose preventing cutter destruction. The limit stress materials for developed endmilling hard-alloy having an interfaced cutting part tailpiece were investigated. was made a tool-grade hard alloy, structural steel. To determine stresses, simulation modelling carried out A...

In the current conditions, there is a multifaceted urgent problem of meeting growing demand agriculture for modern and high-quality equipment. Mulchers tractors, excavators skid steer loaders are becoming more popular as type attachment. Carbide cutting elements mulcher have high resource, do not require sharpening, afraid small stones in soil. An task terms import substitution organization the...

CA 125 is found in body fluids in a variety of molecular weight forms. The largest species are found in normal abdominal fluid and cervical mucus. The present study therefore incorporated CA 125 derived from these sources as well as ascites fluid to investigate if the source of CA 125 influenced epitope characterization. Ascites-derived CA 125 varied in size from about 190 to about 2,700 kD. Ce...

The nucleotide sequences of heavy and light chains from 10 monoclonal IgM anti-IgG1 (RF) antibodies were determined and reported here as translated amino acid sequences. Only three families of VK light chains were used in these antibodies: VK1 (two examples), VK8 (three examples), and VK19 (four examples). This represents a significant nonrandom selection of light chains. In contrast, all other...
