Abstract
The weapon barrel is exposed to strong thermal, mechanical and chemical effect of the powder gasses and the projectile. That causes the appearance of the intensive wear process of the barrel bore. In this paper the analysis of the samples' chemical composition is performed, the metallographic structure of the samples' material is imaged, the possible modification of the barrel bore surface is tested and the hardness over the samples cross section was measured. The hardness of the barrel material is one of the essential factors which contribute to increased barrel's wear resistance. Therefore, modelling of HV5 hardness as a function of the chemical composition of materials was conducted. Determined correlations should allow an easier selection of the wear resistant barrel material as well as the material of other parts of the artillery weapons, with the need to establish a small number of influential parameters, without carrying out extensive tests.
