前言随着我国社会主义建设和国防建设的蓬勃发展,在高峰负荷发电、天燃气输送管线加压站、高原列车等各方面都需要大量的地面燃气轮机。另外,燃气轮机有功率大、重量轻、体积小、启动快和机动性好的特点,用燃气轮机装备海军,提高军舰的战斗力是海军的发展方向。这些地面和舰用的燃气轮机,由于使用低质燃料或者吸入海盐气氛。产生了严重的燃气腐蚀,必须采用耐热腐蚀的高温合金作其涡轮叶片。国外,工作温度高于800℃长期使用的耐热腐蚀高温合金,例如:IN—738,IN—
Preface With the vigorous development of China’s socialist construction and national defense construction, a large number of ground-based gas turbines are needed in all aspects of peak load power generation, natural gas pipeline pressurization stations and plateau trains. In addition, the gas turbine has the characteristics of large power, light weight, small volume, quick start and good maneuverability. It is the navy’s development direction to equip the navy with a gas turbine and improve the combat effectiveness of the warship. These ground and ship gas turbines are used due to the use of low-quality fuels or inhalation of the sea-salt atmosphere. Produced a serious gas corrosion, the use of high temperature alloy corrosion resistant heat turbine blades. Foreign, working temperature above 800 ℃ long-term use of heat-resistant corrosion superalloy, for example: IN-738, IN-
