    • A piston with a cast bi-metallic dome feature and a method of making the piston. In one form, the piston is for use in a diesel engine, while in another, the piston is for use in a gasoline engine. The dome feature may include a laminate of a relatively high-temperature material (such as stainless steel) and a relatively low temperature material (such as aluminum or aluminum alloys) such that the portion of the dome made from the relatively high-temperature material is directly exposed to combustion within a cylinder into which the piston is placed. In another form, an aluminum coated stainless steel layer is used to form the dome. In one form, an ablation casting process may be used to manufacture the dome.
    • 具有铸造双金属圆顶特征的活塞和制造活塞的方法。 在一种形式中,活塞用于柴油发动机,而在另一种形式中,活塞用于汽油发动机。 圆顶特征可以包括相对高温材料(例如不锈钢)和相对低温的材料(例如铝或铝合金)的叠层,使得由相对高温材料制成的圆顶部分是 直接暴露于活塞放置在其中的气缸内的燃烧。 在另一种形式中,使用铝涂层的不锈钢层来形成圆顶。 在一种形式中,可以使用消融铸造工艺来制造圆顶。
