STUDY OF THE WELD DEPOSIT PROPERTIES CONTAINED TUNGSTEN CARBIDES IN THE IRON MATRIX

Popis výsledku v původním jazyce

The components used in the mining and construction industry, agriculture, etc., during its lifetime are exposed to the various types of wear, which include abrasion, erosion, impacts, and others. Currently, there are several variants of protective surface layers which are wear resistance. This group includes special weld deposits combining the metal matrix alloyed with boron and tungsten carbide particle. The parts, hard-faced already in production, can be classified as a group of composite materials that can gradually replace conventional parts made of quality steel. Using these protective layers helps to minimize the cost of repair or replacement of worn parts. The aim of the experiment is to study the properties of the weld deposit with a matrix based on iron with increased content of boron in combination with particles of tungsten carbides of size 1-2 mm using structural steel S235JR as a parent material. The influence of welding parameters, type of matrix and the size of unmelted particles of tungsten carbide was evaluated in terms of the macrostructure assessment, the HV0.1 measurement and the microstructure assessment of selected areas in the view of the possible rate of wear and service life of the weld deposit.
