High-Pressure High-Temperature (HPHT) Autoclave Test:
(1)When the test conditions were a liquid phase of 5% NaCl solution with a pH of 12.5(adjusted using NaOH), a temperature of 148°C, a pressure of 70MPa applied via N , and a duration of 24h, 2the coating exhibited no blistering or softening, and the adhesion remained unchanged.(2)When the liquid phase composition was water, xylene, and kerosene (volume ratio 1:1:1), the gas phasecomposition was 100% CO , and the test was conducted at 107°C under 35MPa for 16h, the coating showed 2no blistering or softening, and the adhesion remained unchanged.
