A piston including a piston crown, the piston crown defining a combustion bowl with a bowl base and bottom surface. A failure initiation structure is provided on the bottom surface of the combustion bowl to initiate favorable fracture at predetermined loads. Such favorable fracture may lead to the a separation of a fragment of the bowl base from the combustion bowl when a predetermined load or pressure is exceeded within the combustion bowl.

Piston for an internal combustion engine and method for producing said piston

A method for laser cladding a material onto a surface of a machine component using a laser scanning head with laser scanning optics is disclosed. The method includes forming a molten bead of cladding material by directing a beam with the laser scanning optics over a bead scan on the machine component. The method also includes directing the beam with the laser scanning optics over a secondary scan on the machine component, the secondary scan being offset from the bead scan at a predetermined distance on the machine component.
