1Cr18Ni9Ti is widely used austenitic heat-resistance steel.High temperature steel is usually used in making the component of at high temperature working in boiler, steam turbine, power machine, industrial furnace and the industrial sectors such as aviation, petrochemical complex.Under complex operating environment, depend merely on it self performance and still can not meet the demands fully, therefore for obtaining better heat-resisting and corrosion resisting property, applying thermal barrier coating (Thermal BarrierCoatings) on its surface is a kind of convenient way.
At present, the structure of thermal barrier coating mainly can be divided into bilayer structure, three kinds of structure formations of multilayered structure and gradient-structure.Bilayer structure mainly contains ceramic surface and tack coat is formed, because bilayer structure is simple, and mature preparation process, thermal boundary is effective, widespread use at present.
The bonding layer material of widespread use at present is the NiCrAlY powdered alloy.The thermal expansivity of NiCrAlY powdered alloy is between matrix and ceramic layer, can relax the thermal stresses between the two, in use, preferential and the oxygen of Al element in the metal bonding coating reacts, generate one deck compact oxide (TGO), can hinder further entering of oxygen, play antioxygenation.But along with the increase of duration of service, oxygen slowly infiltrates, further with tack coat in metallic element react, zone of oxidation (TGO) is thickened, unrelieved stress accumulation, when stress accumulation to a certain degree the time, disbonding, coating lost efficacy.The top layer stupalith that uses is 8wt%Y at present
2O
3-ZrO
2(8YSZ) stupalith, this top layer ceramic heat-barrier coating has lower thermal conductivity, higher thermal expansivity and good thermal-shock resistance, but the life-time service temperature can not surpass 1200 ℃, and the too high meeting of temperature causes 8YSZ phase transformation aggravation, is sintered easily, the oxygen conduction velocity increases, metal bonding coating is oxidized easily, thereby causes coating shedding to lose efficacy, and has been difficult to satisfy the needs that turbine intake temperature further improves.
At present the research of rare earth zirconate is mainly concentrated on the zirconate A of pyrochlore constitution
3+ 2B
4+ 2O
7,, rare earth zirconate has the thermal conductivity lower than 8YSZ, higher high-temperature stability.
Preparing with the glass coating with electrophoresis codeposition-sintering process on the steel matrix surface is tack coat, and rare earth zirconate is the method and the coating structure of the thermal barrier coating on top layer, does not at home and abroad appear in the newspapers as yet.
