Figure 2 is a view showing the structure of the thermal barrier coating layer according to the present invention further deposited Al 2 O 3 layer.
Figure 3 is an enlarged photo of the cross section of the thermal barrier coating layer according to the present invention in one embodiment.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a view showing the structure of the thermal barrier coating layer according to the present invention.

As shown, the heat shield coating layer according to the present invention,

NiCrAl bonding layer 110 formed on the surface of the base material 100; And an YSZ layer 120 positioned on the surface of the NiCrAl bonding layer 110 to represent a main function of heat shielding.

At this time, the YSZ means Yttria Stabilized Zirconia (YSZ), and is a ceramic component prepared to maintain yttria (yttrium acid) in zirconia (zirconium oxide) to maintain stability even at room temperature.

The NiCrAl bonding layer 110 is composed of nickel (Ni), chromium (Cr), and aluminum (Al). The nickel (Ni) is an element having high strength, high temperature creep resistance, surface stability, corrosion resistance, and oxidation resistance. The chromium (Cr) is an element excellent in oxidation resistance and sulfidation resistance, and the aluminum (Al) forms an gamma prime (γ ') phase and is excellent in hardness and oxidation resistance.

That is, the NiCrAl bonding layer 110 of the present invention is composed of elements having the above functions, and minimizes residual stress of the coating, adjusts thermal expansion, and improves fatigue resistance and impact resistance, and the like. It acts as a junction between heat shields.

In addition, the YSZ layer 120 is composed of ZrO 2 (zirconia) and Y 2 O 3 (yttria), which is a ceramic component, the ZrO 2 is a low thermal conductivity compound is excellent in heat shielding, the Y 2 O 3 Is a compound that stabilizes by inhibiting the tissue change of the ZrO 2 with temperature changes.

That is, the YSZ layer 120 of the present invention is composed of compounds having the above functions, and serves as a heat shield layer for blocking heat release to the outside and improving corrosion resistance, heat resistance, and oxidation resistance.

At this time, the YSZ layer 120 is Y 2 O 3 It is preferred to include 6 to 9% by weight and the balance ZrO 2 , Y 2 O 3 relative to the total weight of the YSZ layer 120 When the weight is less than 6%, the ZrO 2 structure change due to temperature change cannot be sufficiently suppressed, so that the high temperature stability is lowered, and when the weight exceeds 9%, ZrO 2 exhibits a heat shielding effect. This is because the content is relatively reduced, so that sufficient thermal barrier effect cannot be expected.

On the other hand, the NiCrAl bonding layer 110 preferably has a thickness of 20 to 200 μm, when the thickness is less than 20 μm, the bonding strength is less than 5MPa and the bonding strength between the base material 100 and the YSZ layer 120 is insufficient. This is because the peeling phenomenon of the coating layer occurs, and when the bonding layer exceeds 200 μm, the bonding effect is saturated to about 30 MPa.

In addition, the YSZ layer 120 is preferably having a thickness of 100 to 400 μm, when the thickness is less than 100 μm heat shielding temperature is less than 10 ℃ bar heat shielding coating effect is insignificant to be used in the engine exhaust system, If it is over 400 μm, the heat shield temperature is over 40 ℃ but it is not suitable for automotive parts due to excessive cost increase.

2 is a view showing the structure of the thermal barrier coating layer according to the present invention in which the Al 2 O 3 layer is further deposited.

As shown, an Al 2 O 3 layer 130 may be added between the NiCrAl junction layer 110 and the YSZ layer 120 as an oxidation resistance reinforcing layer for enhancing oxidation resistance.

Specifically, the Al 2 O 3 layer 130 preferably has a thickness of 20 to 200 μm. When the thickness is less than 20 μm, the oxidation resistance reinforcement effect is higher than that of the heat shield coating layer before the Al 2 O 3 layer 130 is added. If the value is less than 200 μm, the oxidation resistance effect is saturated compared to the required oxidation resistance standard.

On the other hand, there is a thermal spraying method of coating the surface of the metal base material with a coating material.

The spray coating technology is classified into flame, arc, plasma and explosion spray according to the heat source for melting the coating material prepared in the form of wire or powder. The present invention is particularly concerned with the high voltage generated between the anode and the cathode inside the spray case. By using plasma forming gas (mainly argon or nitrogen) as a heat source, it uses a plasma spray coating technique, which is a spray coating technique suitable for coating a ceramic having a high temperature melting point.

Specifically, the outer or inner diameter of the engine exhaust system, that is, the surface of the base material 100 is activated by sand blasting, and then the NiCrAl bonding layer 110 is 20 to 200 μm thick by using a plasma spray coating technique on the surface of the base material 100. To be deposited.

Then, Y 2 O 3 using a plasma spray coating on the surface of the formed NiCrAl bonding layer 110 YSZ layer 120 comprising 6-9 wt% and the balance ZrO 2 is deposited to a thickness of 100-400 μm.

At this time, the Al 2 O 3 layer 130 is deposited to a thickness of 20 to 200 μm using a plasma spray coating technique on the surface of the formed NiCrAl junction layer 110 before the YSZ layer 120 is deposited for oxidation resistance. can do.

Figure 3 is an enlarged photo of the cross section of the thermal barrier coating layer according to the present invention in one embodiment.

As shown, NiCrAl bonding layer 110 is deposited on the surface of the base material 100 to a thickness of 100 μm, Y 2 O 3 on the surface of the NiCrAl bonding layer 110 An YSZ layer 120 comprising 8 wt% and the balance ZrO 2 is deposited to a thickness of 200 μm.

Table 1 is a table measuring the heat shielding effect of the exhaust system components coated with a heat shield coating layer according to an embodiment of the present invention at a temperature shielded according to the temperature of the exhaust gas.

As shown in Table 1, the heat shield temperature is also increased in proportion to the increase in the exhaust gas temperature, it can be seen that the heat shield effect of about 19 to 20 degrees per 100 ℃ by the heat shield coating layer.

Figure pat00001

Table 2 is a table comparing the heat shielding effect of the exhaust system components coated with the heat shield coating layer according to the embodiment of the present invention compared with the conventional exhaust system components.

As shown in Table 2, after applying the heat shield coating layer according to the present invention, it can be confirmed that the surface temperature is reduced as a result of measuring the temperature of the peripheral parts such as elbow hose or Wastegate can, which is a heat shield according to the present invention Coating layer, especially Y 2 O 3 This is because the thermal barrier property is greatly improved by the YSZ layer 120 including 8 wt% and the balance of ZrO 2 .

Applicable parts Initial temperature (℃) Final temperature (℃) Cycle result Turbine housing 400 20 10 no problem Exhaust manifold 600 20 10 no problem Muffler 800 20 24 no problem

Table 3 is a table showing the thermal shock test results of the exhaust system components coated with the heat shield coating layer according to the embodiment.

As shown in Table 3, the exhaust system components to which the heat shield coating layer according to the present invention was applied were heated to an initial temperature, then left to stand for 1 hour and quenched to a final temperature. Did not appear.

This means that the thermal shock resistance of the thermal barrier coating layer according to the present invention is excellent, and can be applied even in a severe exhaust system environment.

As described above, the heat shield coating layer according to the present invention is excellent in heat resistance and oxidation resistance, heat resistance, and hardness, in particular, to reduce thermal damage of components around the engine exhaust system, and to apply to an SCR system to improve fuel efficiency of a vehicle.
