Lukluk gut long dispela tebol. Antap long liklik 'bump' long 'Carbon', M35 em i M2 tasol we ol i kapsaitim 'Cobalt' insait long 'melt'.
Orait, Cobalt i save mekim wanem samting tru?
Em hia gutpela hap:Kobalt i no save kamapim ol 'carbides'.I no olsem Tungsten o Vanadium, we i save kamapim ol strongpela liklik ston insait long ain bilong pasim bagarap, Kobalt i save kapsait olgeta insait long ain matriks.
Taim em i sindaun insait long 'matrix', Cobalt i save apim 'melting point' bilong 'internal structure' bilong 'steel'. Em i wok olsem wanpela 'metalurgical scaffolding'. Taim tul i kamap hat nogut tru long 'friction', 'Cobalt' i save pasim 'grain structure' bilong 'steel' long pundaun.
Insait long wok bilong masin, ol i kolim dispela samting"Red Hardness" (o Hot Hardness).

Olsem na, taim dril i traim long subim i go insait moa, wantu em i traim long katim samting we i hat moa long wanem em i bin stap liklik hap bilong wanpela seken i go pinis.
Dispela i kamapim bikpela kros. Bikpela friksen i save kamapim bikpela hat.
Scenario A: Yusim m2 hai spit ain long Steinles
Yu statim CNC program. M2 dril i paitim 'stainless'. Hat i go antap. Bikos M2 i no gat bikpela Red Hardnes olsem Cobalt i save givim, 'cutting edge' bilong dril i save kamap hariap long tempereja bilong en. Arere bilong en i kamap malumalum, i tanim i go antap, na dril i stop long katim. Nogat, em i save rapim tasol long 'stainless', na kamapim moa hat inap long em i bruk o melt.
Scenario B: Yusim stretpela 'high speed steel' bilong 'stainless' (M35)
Yu senisim tul wantaim wanpelam35 kobalt ainliklik hap. Hat i wok long go antap yet-yu no inap senisim ol lo bilong fisiks.

Dispela em i as na, sapos stua bilong yu i wok long Inconel, Titanium, o 300-series alloys, olgeta manmeri i save luksave long M35 olsem nambawanhai spit ain bilong steinles.
Nogutpela samting bilong kobalt (bilong wanem moa i no gutpela oltaim)
Long dispela point, ating yu ting:"Sapos Cobalt em i gutpela tru, bilong wanem yumi no wokim olgeta samting long M35, o putim 10% Cobalt?"(Spoiler: Em i stap, nem bilong en M42).
Em hia 'engineering trade-off':Taim Red Hardness i go antap, Toughness i go daun.
Bikos Kobalt i save apim tempereja,m35 hai spit ainem i save bruk bruk moa longm2 hai spit ain.
Sapos yu yusim wanpela han dril o wanpela dril pres we i no stap gut liklik, ol 'lateral vibrations' inap long brukim wanpela M35 dril bit long tupela hap. M2, em i strong moa na i save tanim tanim liklik, em bai stap laip long dispela guria.
Na tu, M35 em i hat long grisim. Long ol kampani i wokim ol tul, wok bilong wokim ol 'end mill' long M35 i save kisim moa taim na i save bagarapim ol 'grinding wheels'spit moa long M2. Dispela i save apim pe bilong wokim ol samting antap long pe bilong ol samting bilong wokim ol samting.
