Abstract

Cilj ovoga rada je karakterizacija materijala koji se koriste za izradu lista kružne pile za skidanje gipsa u medicini. Rad se sastoji od literaturnog pregleda svojstava i sastava alatnih čelika te eksperimentalnog dijela. Teoretski dio sadrži opis nehrđajućih alatnih čelika s naglaskom na martenzitne, koji imaju svoju primjenu u medicini kao kirurški instrumenti. Eksperimentalni dio se sastoji od karakterizacije materijala lista kružne pile za skidanje gipsa s ciljem pronalaženja uzroka njegovog preranog dotrajavnja. U tu svrhu određen je sastav materijala kružne pile, napravljena je kvantitativna i kvalitativna analiza strukture te je izmjerena mikrotvrdoća i makrotvrdoća materijala. Nakon provedene analize obrađeni rezultati su sumirani te su postavljeni određeni zaključci o strukturi i tvrdoći lista kružne pile koja se upotrebljava u medicini za skidanje gipsa.

Abstract (english)

The aim of this paper is to characterize the material used for making circular saw blade for removing of plaster in medicine. The work is consists of literature review of properties and composition of tool steels and experimental part. The theoretical part contains a description of stainless steel tools with a focus on martensitic which have their applications in medicine, as well as surgical instruments. The experimental part consists of materials characterization of circular saw blade for removing plaster with a view to finding the cause of his premature wear. For this purpose, composition of the material of circular saws was given as well as quantitative, qualitative, micro-hardness and macro-hardness of the materials was measured and determined. Following the analysis, processed results are summarized and conclusions are placed on the structure and hardness of the circular saw blade that is used in medicine to remove the plaster.
