Abstract. There is increasing interest in the use of advanced ceramic
in machine building. This is primped by the attractive properties of ceramics
such as good high temperature, strength, low thermal conductivity, chemical
inertness, high hardness and also good tribological properties - low wear
and low friction. On the other hand near the honing and grinding it is
possible to obtain high precision surfaces using lapping and polishing.
This paper intend to find the most propitious for advanced ceramics by
changing the normal load speed and the size of lapp medium. The samples
used was the Al2O3-99.7%-RK38. After lapping the
surfaces roughness was measured using Perthometer device and the wear was
measured using the weight loss method requires careful weighting of samples
before and after test, using an electronic microbalance.
USLOVI KOJI OPREDELJUJU TAČNOST
KERAMIČKE POVRŠINE PRI POVRŠINSKOM LEPOVANJU
Ovaj rad ima za cilj pronalaženje najpovoljnijeg medijuma za lepovanje
savremenih keramičkih materijala i to variranjem normalnog opterećenja,
brzine i krupnoće (granulacije) medijuma za lepovanje. Eksperimentalna
ispitivanja su vršena na uzorcima od Al2O3-99.7%-RK38.
