Ballistic Impact Behavior of Multilayered Armor Plates Processed by Hardfacing

摘要

Hardfacing is a type of surface treatment for the extension of service life of worn parts or structures and the improvement of the surface properties through deposition of the alloys using arc welding or laser cladding. Among the hardfacing alloys, the high chromium hardfacing alloys have been used most extensively for dies or parts in various industrial areas because of their excellent hardness, corrosion resistance, and wear resistance as well as inexpensive-ness. These properties are obtained from the large volume fraction of hard chromium carbides. The recent works on these alloys have focused on the property enhancement, the microstructural modification, and the high-temperature application.
