Faodar plàta tiugh meadhanach ASTM A240 304 316 a ghearradh agus a ghnàthachadh prìs factaraidh Sìona

Seòrsa: Ferrritaic, Clàraich, Martenite, DUPLEX
Teicneòlas: Rolled fuar agus teth air a roiligeadh
Teisteanasan: iso9001, CE, Sns a h-uile bliadhna
Seirbheis: Deuchainn treas pàrtaidh

Usually they have a low hardness (in the range of 180 to 450 HV), only some heat treated martensitic stainless steels have high hardness (up to 700 HV) and high carbon content (up to 1.2 wt%), which can contribute to the cruthachadh martensenite.




In addition, specimens of EBM-treated high-carbon martensitic tool steel (HCMTS) with a nominal chemical composition of 1.5 C, 4.0 Cr, 2.5 Mo, 2.5 W, 4.0 V, 85.5 Fe (wt. .%) (commercially known as Vibenite® 150) Chaidh ullachadh cuideachd a dheasachadh san aon dòigh.







Tha mi fhìn mhiorrachadh HCMSS a tha air a làimhseachadh le Elp air a dhèanamh suas de lìonra dùmhail aon-chànanach air a chuairteachadh le matrix (Fig. 2A, b).Sheall mion-sgrùdadh Edx gur e clach-sgaoilidh làn chromium agus bhana-bheairteach (Clàr 1).Is e na meudan gràn cuibheasach le gluasadan àbhaisteach 0.64 ± 0.2 μm agus 1.84 ± 0.4 μm airson v agus gend. 2c, D).An coimeas ri sin, chan eil baidhsagalan-ùreann àrd-chromium cruinn timcheall, le feart cumadh timcheall air 0.56 ± 0.01, a dh 'fhaodadh a bhith mar thoradh air àrd-chuinneachaidh.Chaidh na Martenesite (α, bcc) agus an Austenites) a chaidh a ghleidheadh ​​(γ ', FCC) air a lorg air pàtran X-Ray HCMSS mar a chithear ann am Fig. 2e.A bharrachd air an sin, tha an pàtran x-ghath a 'sealltainn làthaireachd slabhraidhean àrd-sgoile.Chaidh baisteadairean droma High Chromium a chomharrachadh mar bhàistean de bhuidseach seòrsa M3C2 agus M23C6.


chan eil e ag atharrachadh gu sgiobalta.The decrease in CoF with increasing load in steady state (about 14.1%) can be attributed to surface degradation occurring at the interface between the worn surface and the counterpart, which will be further discussed in the next section through the analysis of the surface of the Sampaillean caite.


Tha an sgaptpot a 'sealltainn an claonadh coitcheann nam tomhais.Thathas a 'toirt dàta airson diogan austenitic a thoirt bho 8.
obair air a 'phàirt deireannach;
5, far a bheil am prìomh uidheam air a briseadh le spionnadh air a leantainn le oxidation.An toiseach, tha an substrate stàilinn air a dhìoladh gu planical agus an uairsin air a thoirt air falbh gus Grooves a chruthachadh 1 gu 3 μm domhainn, mar a chithear anns a 'phròifil uachdar (Fig. 5A).), mar a chaidh aithris cuideachd airson stàilinn austenticuic a chaidh a làimhseachadh le l-pbf15,17.Tha 5c a 'sealltainn dian oxitation a' tachairt ann am meadhan an sgarfa.
Surface profile (a) and photomicrographs (b–f) of the wear surface morphology of high-carbon martensitic stainless steel treated with ELP at 3 N, cross-section of the wear mark in BSE mode (d) and optical microscopy of the wear uachdar aig 3 n (g) speuragan alumina.


Surface profile (a) and photomicrographs (b–f) of worn surface topography (b–f) of high-carbon martensitic stainless steel treated with EBA at 10 N, wear track cross-section in BSE mode (d) and optical microscope surface de alumina sphere aig 10 n (g).




Bidh an luach cofaidh a 'lughdachadh le luchd a' sìor fhàs mar thoradh air gluasad stuth chun a 'bhuidheann eile.A 'cleachdadh a' mhodh mapaidh cron-luachmhachaidh thar-roinn, tha Sòn an Deitidh Plastaig air a shealltainn fo an comharra caitheamh.
