The present invention discloses a partial reinforced particle piston and a manufacturing method thereof. The partial reinforced particle piston comprises a head, a skirt section and a pin base. The head comprises a piston top and a ring slot part. The piston top and the ring slot part are reinforced areas which are formed by distributing reinforced particles in piston matrix material. The skirt section is an non-reinforced area. The reinforced area and the non-reinforced area are combined by an alloy combination form. The partial reinforced particle piston not only increases the wearing resistance of the head of a piston and reduces the thermal expansion coefficient, but also ensures the good mechanical performance of the skirt section of the piston and realizes the continuous transition of the organization structure and performance of the partial reinforced area and the non-reinforced area; the effective power of an engine is improved; the service life of the piston is prolonged; in order to manufacturing the piston, the present invention uses a centrifugal casting method to assemble the reinforced particles in melted homogenous composite material at the head of the piston, and the manufacturing method has simple technology and low manufacturing cost.
