Abstract

Przedmiotem zgłoszenia jest przedstawiona na rysunku wkładka kompozytowa pod rowek pierścienia tłoka silnika spalinowego o kształcie krążka, w której osnowę wkładki stanowi stop aluminium, a wzmocnieniem są ceramiczne cząstki węglika krzemu lub cząstki tlenku aluminium, przy czym średnica cząstek ceramicznych ma wymiar nie większy niż 30 mikrometrów optymalnie 20 mikrometrów, a udział objętościowy w osnowie aluminiowej wynosi do 50%, zaś powierzchnia wkładki jest ukształtowana w ten sposób, że ma obniżony stosunek objętości do powierzchni odbioru ciepła, względem powierzchni płaskiej, korzystnie powierzchnia jest falista w kierunku równoległym albo prostopadłym w stosunku do czoła wkładki. Przedmiotem zgłoszenia jest także zastosowanie wkładki w produkcji tłoków silnika spalinowego.The subject of the application is the composite insert presented in the figure for the groove of a piston ring of a combustion engine in the shape of a disc, in which the matrix of the insert is an aluminum alloy, and the reinforcement is ceramic silicon carbide particles or aluminum oxide particles, the diameter of the ceramic particles being not larger than 30 micrometers optimally 20 micrometres, and the volume share in the aluminum matrix is up to 50%, while the surface of the insert is shaped in such a way that it has a reduced ratio of volume to heat reception surface, relative to a flat surface, preferably the surface is wavy in a direction parallel or perpendicular to face liner. The subject of the application is also the use of an insert in the production of pistons in an internal combustion engine.
