Testing Projectile Rotating Bands Made of Iron Powder with WS2

<ns3:p>This article presents the results of experiments on rotating bands manufactured from iron powder, with the addition of tungsten disulfide (WS₂). Test samples were produced using different compaction pressures and varying amounts of the WS₂ lubricant. In the initial stage of the study, properties such as porosity, density, selected mechanical characteristics, and friction coefficient were measured. These results enabled the optimisation of the rotating band manufacturing process. In the subsequent phase, rotating bands were fabricated and assembled onto projectiles. Push-through force tests were then conducted to assess the behaviour of the rotating bands under quasi-static conditions. The results demonstrated that the addition of a lubricating material lowers the friction coefficient and reduces both engraving and push-through forces.</ns3:p>
