A bi-metal variable geometry turbocharger (VGT) blade includes a flag portion of a structural airfoil shape and a shaft portion of a functional cylindrical shape connected to the flag portion. The flag portion and the shaft portion are formed of a first metal alloy, and the shaft portion further includes a surface region formed of a second metal alloy different from the first metal alloy. 一种双金属可变几何形状涡轮增压器(VGT)叶片，包括结构性翼型件形状的旗部部分和连接到旗部部分的功能性的柱形形状的轴部分。旗部部分和轴部分由第一金属合金形成，并且轴部分还包括由不同于第一金属合金的第二金属合金形成的表面区域。
