Structure and properties of steel coating ligated titanium

Abstract

The paper presents experimental results on the structure and properties of coatings obtained while spraying a titanium cathode and cathode steel 12X18H10T. Coatings were deposited in argon and nitrogen on a substrate 45. The coating of steel 12X18H10T + Ti in a nitrogen gas atmosphere containing 73 % Ti, and the coating 12X18H10T + Ti in an argon gas atmosphere has a high content of Fe — 64,96 %. 12X18H10T + Ti coating in an atmosphere of nitrogen gas and argon have a columnar structure characteristic of single phase films. Covering 12X18H10T + Ti in a gaseous environment of nitrogen has nanohardness equal to 35.808 GPa and argon — 3.339 GPa. The difference obtained by 10 times. Our experimental results indicate that the nanohardness 12X18H10T + Ti coating in an atmosphere of nitrogen determined nanoscale titanium nitride whose dimensions lie in the range (5–10) nm.
