Structural Analysis of Carabiners Materials Used at Personal Protective Equipments

Abstract

Thus specialized shackles are used in severe environment condition, such as: temperature variation (firefighters, mountain climbers), highly corrosive (construction, caving, sailing), etc. so it must be manufactured from materials with good corrosion resistance and refractoriness. Because the carabiners are used at height, besides the properties already exposed, they must possess properties of resilience. This paper presents a metallographic analysis using Scanning Electron Microscope and Energy Dispersive Analysis X-ray to highlight the structural characteristics in order to increase resilience and improve the wear and corrosion resistance properties.
