Sintered gas filters

Sinterirani metalni filteri u praksi se koriste već duži niz godina. Primjenu ostvaruju u brojnim industrijama. Široko područje primjene ostvaruju na osnovu svojih dobrih svojstava. U izradi sinteriranih metalnih filtera najviše se primjenjuje prah bronce. Iz tog razloga je u prvom dijelu ovog rada stavljen naglasak na legure bakra i njihova svojstva. Zatim se prikazuju glavne značajke metalurgije praha pri izradi brončanih filtera. U eksperimentalnom dijelu rada opisan je postupak izrade sinteriranih uzoraka primjenom različitih zaštitnih atmosfera. U zadnjem dijelu rada provedeno je ispitivanje savojne čvrstoće izrađenih uzoraka, te su doneseni određeni zaključci.Sintered metal filters have been used in practice for many years. They are used in many industries. Based on their good properties, they are used in many production plants. Bronze powder is the most used in the production of sintered metal filters. For this reason, the first part of this paper emphasizes copper alloys and their properties. The main characteristics of powder metallurgy during the production of bronze filters are then presented. The experimental part of the paper describes the procedure of production of sintered samples using different protective atmospheres. In the last part of the paper, the flexural strength of the produced samples was tested, and some conclusions were made
