Influence of CaSi_2 and Si additions on properties of coatings produced by plasma spraying of composite powders

摘要

Addition of CaSi2 in steel melt leads to a decrease of oxygen content, an increase of the melt flowcapability, an improvement of a metal ductility and weldability. For an estimation of CaSi2 and Si additions effect in conditions of thermal spraying composite powders were produced. A base material of these powders particles is nickel, nichrom and iron. CaSi2 and Si are additional components of the powders (3-12 wt.
