Abstract

Inventia se refera la o compozitie de pasta pentru durificare a pieselor din otel ce asigura dupa aplicare îmbogatirea în carbon a straturilor de aliaj depuse ulterior, contribuind la cresterea rezistentei la uzura a straturilor depuse prin sudare. Compozitia este constituita dintr- un amestec de 75...80% carbon sub forma de grafit pulbere cu granulatie mai mica de 0,2 mm, 20...25% carbonat de sodiu pulbere fina si 1...5% hidroxid de calciu utilizat sub forma de lapte de var. Amestecarea componentelor se face pîna ce se obtine o consistenta a pastei ce permite aplicarea sa prin pensulare pe suprafetele tari.The invention relates to a paste composition for hardening of steel parts which after application of the carbon enrichment of the deposited alloy layers, contributes to the increase of the wear resistance of the deposited layers. The composition consists of a mixture of 75 ... 80% carbon in the form of powder graphite with a grain size of less than 0.2 mm, 20 ... 25% fine powder sodium carbonate and 1 ... 5% calcium used as lime milk. Mixing the components is done until a consistency of the paste is achieved which allows it to be applied by brushing on hard surfaces.
