Sažetak
U radu je dat pregled literaturnih podataka o istraživanjima uticaja sloja vanadijum karbida deponovanog Toyota difuzionim postupkom na povećanje radnog veka i kvaliteta alata za obradu kovanjem. Kalupi za kovanje podvrgnuti su teškom adhezivnom i abrazivnom habanju, visokim naponima i temperaturama. Površina kalupa i region u blizini površine podvrgnuti su najtežim uslovima tokom obrade kovanjem i s toga većina defekata i uzroka destrukcije potiču iz ovog regiona. Zbog toga, rad uzima u razmatranje i različite komplikovane mehanizme habanja i destrukcije površine alata za obradu kovanjem, odnosno onu mrežu različitih aspekata koji utiču na vek trajanja alata a koji svojim delovanjem prouzrokuju prevremeno uklanjanje alata iz upotrebe.
Abstract
In this paper is given a review of literature data about research of influence layer of vanadium carbide deposited by Toyota diffusion process on increasing of working life and quality of forging dies. Forging dies are subjected to severe adhesive and abrasive wear, high stresses and temperatures. The die surface and near surface region is subjected to the most severe conditions during forging and hence most defects and causes of failure of the dies originate from this region. Because of this, paper takes into consideration the different complicated mechanisms of wear and the destruction of the surface of tools for forging, apropos that network of various aspects which affect on the service life of the tool and by their actions causing premature removal tool from the use.
