Admiscetur dura ex carbide tungsten

Abstract

Agro: metallurgia.

SUBSTANTIA: inventio campi metallici pulveris refertur.Praecipue pertinet ad recipiendum offensionis sinterae duram ex carbide tungsten.Poni potest ad caedendum, terebras et lembos molendos.Mixtura dura continet carbidam et 18.0-20.0 % tungstenum cum ligatura.Molybdenum 48.0-50.0;niobium 1.0-2.0;rhenum 10.0-12.0;cobalt 36.0-41.0.

ECFECTIO: Summus robur susceptionis offensionis.

Descriptio

Inventio spectat ad campum pulveris metallurgiae et ad sintedi duriores mixtiones producendas in carbide tungsten, quae adhiberi possunt ad fabricandum lignarios, terebras, molendina et alia instrumenta.

Notae carbidi sinteratae innixa carbide tungsten, continens 3.0 ad 20.0 s.molybdenum - usque ad 5.0;niobium – usque ad 3.0 [1].

Objectum inventionis est offensionis robur augere.

Effectus technicus consequitur in eo quod in sinteredo duriori innixa carbide in tungstena continente 80.0-82.0 wt.% Tungsten carbidam et 18.0-20.0 wt.% Ligans, ligans continet, %: Molybdaenum 48 0-50,0;niobium 1.0-2.0, rhenum 10.0-12.0;cobalt 36.0-41.0.

In schemate.I ostendit compositionem mixturae, sicut etiam ultimam virtutem in inflexione.In schemate.2 compositionem ligamenti ostendit.

Table 1 Components Compositio, wt%: una 2 3 Wolfram carbida 80.0 81.0 82.0 Bunch 20,0 19.0 18.0 Tendens Virtus, MPa ~ 1950 ~ 1950 ~ 1950

Tabula 2. Components Compositio, %: una 2 3 Molybdenum 48.0 49.0 50,0 Niobium 1,0 1,5 2.0 Rhenium 10.0 11.0 12.0 Cobalt 41.0 38.5 36.0

Pulveres mixturae mixtae in proportionibus indicatis, mixtio pressa 4.5-4.8 t / cm 2 et sinterae in fornace electrica ad temperiem 1300-1330 °C in vacuo per 7-9 horas.Per sintering, ligans carbide spontaneam partem dissolvit et dissolvit.Effectus est materia densa, cuius structura tungsten consistit in particulis carbide ligante connexis.
