The invention provides a novel piston and a manufacturing method of the novel piston. The novel piston comprises a piston body and a piston head. The piston head is embedded to the end of the piston body. The axial end face on the inner side and the axial end face on the outer side of the piston head are provided with a thermoplastic polyimide layer and a ceramic coating correspondingly. Comparedwith the prior art, the novel piston has the following beneficial effects that the structure is simple, no piston ring is arranged, the structure is more simple, and performance is more reliable; thepiston is lighter, and therefore the transmission efficiency of an engine is higher; the novel piston is better in wear resistance, lower in friction coefficient and longer in service life compared with a piston ring structure; and unique modified thermoplastic polyimide is adopted; and at 250 DEG C or below, the size is stable, and linear expansion coefficient is kept the same as an aluminum alloy.
