Description
Opis wynalazkuDescription of the invention
Przedmiotem wynalazku jest stop eutektyczny wieloskładnikowy zawierający żelazo, mangan, węgiel, bor, krzem, nikiel i chrom.The subject of the invention is a eutectic multicomponent alloy containing iron, manganese, carbon, boron, silicon, nickel and chromium.
Wykorzystywane powłoki odporne na zużycie są najczęściej otrzymywane na bazie Co, Ni, Fe,The wear-resistant coatings used are most often obtained on the basis of Co, Ni, Fe,
Ti. Przykładem mogą być stopy Fe-C-Cr-Si - K. Granat, „Wieloskładnikowe stopy Fe-C-Cr-Si odporne na zużycie przeznaczone na odlewy i warstwy napawane”. Oficyna Wydawnicza Politechniki Wrocławskiej, Wrocław 2005 lub Fe-Ti-V-Mo-C - X. Wang, F. Hanb, X. Liu, S. Qu, Z. Zou, „Microstructure and wear properties of the Fe-Ti-V-MoC hardfacing Allom”, Wear vol. 265, 2008, s. 583-589. Dotychczas znane są układy o charakterze eutektycznym, które uzyskuje się między innymi w stopach Fe-C, Fe-B, Fe-Mn-C, Fe-Cr-C, Fe-Ni-C, Fe-Mn-C-B, Fe-Mn-C-B-Si. Tworzenie obszarów eutektycznych spowodowane jest oddziaływaniem takich pierwiastków jak Fe, Mn, C, B. Przy ich otrzymywan iu dąży się do podwyższania plastyczności warstw wierzchnich przy zapewnieniu ich wysokiej twardości. Osiąga się to poprzez stopowanie pierwiastkami zwiększającymi twardość i plastyczność powłok. Właściwości tribologiczne zwiększa się poprzez otrzymanie w strukturze stopów węglików żelaza, manganu oraz borków żelaza, takich jak Fe3C, Mn3C, Fe2B, FeB. Wykorzystanie Fe2B, FeB jako faz dyspersyjnych w strukturze stopu podyktowane jest ich wysoką twardością, odpornością na zużycie, korozję i stabilnością termiczną. Dodatek manganu zwiększa plastyczność węglika żelaza Fe3C poprzez formowanie manganowego węglika żelaza Fe0,4Mn3,6C.Ti. An example is the alloys Fe-C-Cr-Si - K. Granat, "Multi-component alloys Fe-C-Cr-Si resistant to wear for castings and overlay layers". Oficyna Wydawnicza Politechniki Wrocławskiej, Wrocław 2005 or Fe-Ti-V-Mo-C - X. Wang, F. Hanb, X. Liu, S. Qu, Z. Zou, "Microstructure and wear properties of the Fe-Ti-V -MoC hardfacing Allom ”, Wear vol. 265, 2008, pp. 583-589. So far, eutectic systems are known, which are obtained, among others, in alloys Fe-C, Fe-B, Fe-Mn-C, Fe-Cr-C, Fe-Ni-C, Fe-Mn-CB, Fe-Mn -CB-Si. The formation of eutectic areas is caused by the interaction of such elements as Fe, Mn, C, B. During their preparation and u, efforts are made to increase the plasticity of the outer layers while ensuring their high hardness. This is achieved by alloying with elements that increase the hardness and plasticity of the coatings. The tribological properties are increased by obtaining iron carbides, manganese and iron borides such as Fe 3 C, Mn 3 C, Fe 2 B, FeB in the structure of alloys. The use of Fe 2 B, FeB as dispersion phases in the alloy structure is dictated by their high hardness, wear resistance, corrosion resistance and thermal stability. The addition of manganese increases the ductility of iron carbide Fe3C by forming manganese iron carbide Fe0.4Mn3.6C.
Istotą stopu eutektycznego wieloskładnikowego zawierającego żelazo, mangan, węgiel i bor, otrzymywanego znanymi sposobami w postaci proszku do nanoszenia powłok metodami spawalniczymi, w postaci drutu proszkowego, bądź elektrod proszkowych lub jako stop odlewniczy, jest to, że zawiera dodatkowo krzem, nikiel i chrom, przy czym wagowa zawartość manganu wynosi 3,1-14%, korzystnie 7,3%, węgla 1,6-3,2%, korzystnie 1,65%, boru 1,85-2,3%, korzystnie 1,8%, krzemu 1,9-2,7%, korzystnie 2,45%, niklu 8,25-17,7%, korzystnie 17,6%, chromu 10,5-16,25%, korzystnie 16,25%, resztę stanowi żelazo i dopuszczalne zanieczyszczenia w postaci siarki i fosforu w ilości do 0,025%.The essence of a multi-component eutectic alloy containing iron, manganese, carbon and boron, obtained by known methods in the form of a powder for applying coatings by welding methods, in the form of a flux-cored wire or powder electrodes or as a casting alloy, is that it additionally contains silicon, nickel and chromium, the manganese content by weight is 3.1-14%, preferably 7.3%, carbon 1.6-3.2%, preferably 1.65%, boron 1.85-2.3%, preferably 1.8% , silicon 1.9-2.7%, preferably 2.45%, nickel 8.25-17.7%, preferably 17.6%, chromium 10.5-16.25%, preferably 16.25%, the rest it is iron and permissible impurities in the form of sulfur and phosphorus in the amount of up to 0.025%.
Korzystnym skutkiem takiego rozwiązania jest to, że stop może być stosowany na obciążone mechanicznie części maszyn i urządzeń pracujące w warunkach tarcia suchego.The advantageous effect of this solution is that the alloy can be used on mechanically loaded parts of machines and devices operating in dry friction conditions.
Skład fazowy stopu eutektycznego jest następujący: austenit stopowy - faza miękka, manganowy węglik żelaza Fe0,4Mn3,6C - faza wzmacniająca, dyspersyjne wtrącenia borku żelaza Fe2B oraz węglika chromu i żelaza Cr7C3, Fe3C - fazy dyspersyjne. Stop eutektyczny jest materiałem kompozytowym dyspersyjnie wzmocnionym borkami oraz węglikami żelaza z gradientem strukturalnym. Stop charakteryzuje się wysoką odpornością na zużycie.The phase composition of the eutectic alloy is as follows: alloy austenite - soft phase, manganese iron carbide Fe 0 , 4 Mn 3 , 6 C - strengthening phase, dispersion inclusions of iron boride Fe 2 B and chromium and iron carbide Cr 7 C 3 , Fe 3 C - dispersion phases. The eutectic alloy is a composite material dispersion reinforced with borides and iron carbides with a structural gradient. The alloy is highly wear-resistant.
