The thermal reaction of SF 6 with tungsten powder was investigated by thermogravimetry (TG) and differential scanning calorimetry (DSC), combined the characterization solid decomposition products SEM, EDS, XPS Raman. Based on above experiments, a two-stage process proposed: first stage is surface vulcanization W+SF →S 2 , mainly taken place at 600 °C, activation energy valued 152.8 kJ·mol -1 ac...

The paper presents the results of experimental work on assessment 3D geometry surface stereometry obtained as a result Water Jet (AWJ) water-abrasive beam cutting using an Eckert Opal WaterJet COMBO hydro-abrasive cutter. Studies geometric structures were conducted Alicona Infinite Focus microscope. article analyses selected spatial roughness parameters multilayer structure surfaces combined vu...

Ceramifiable styrene-butadiene (SBR)-based composites containing low-softening-point-temperature glassy frit promoting ceramification, precipitated silica, one of four thermally stable refractory fillers (halloysite, calcined kaolin, mica or wollastonite) and a sulfur-based curing system were prepared. Kinetics of vulcanization and basic mechanical properties were analyzed and added as Suppleme...

Starting from a polymeric-fluid droplet, by vulcanization of the fluid free surface, curved elastic membranes, several nanometers thick and a few millimeters in diameter, which enclose a constant fluid volume, are produced. In an indentation-type test, carried out by pushing the membrane along its normal by means of a micro-needle, under some conditions, wrinkles are likely to appear around the...

The aim of the study is to effect gas pyrolysis resin on properties elastomeric composite materials. It has been established that in presence it thiuram vulcanizing system, relative rate vulcanization styrene-butadiene rubber increases, time reach optimum decreases, but degree proportional maximum torque, and when using a sulfur activates process, which facilitated by its composition active fun...
