Cov npib tsib xee phosphorus alloy txheej ntawm cov hluav taws xob cua sov raj ua pov thawj pom tseeb ntse peaks

Tom qab X-ray diffraction tsom xam ntawm cov qauv kho nyob rau hauv ntau yam mob, nws tau pom tias cov nickel phosphorus alloy txheej tom qab kev kho cua sov ntawm 1000 degree thiab 60 vib nas this pom pom tseeb peaks, qhia tau hais tias lub txheej tau undergone crystallization thiab intermetallic compound theem xws li Ni3P tau nag lossis daus. Tshwj tsis yog rau cov xwm txheej ntawm 1000 degree thiab 60s, cov nickel phosphorus alloy txheej tom qab kev kho cua sov ntawm txhua qhov kev ntsuas kub thiab lub sijhawm ua haujlwm tau tswj hwm tus yam ntxwv ntawm cov qauv amorphous zoo li cov txheej txheej txheej, tag nrho hauv 2 θ= Ib qho diffuse ncov zoo nkaus li ntawm 52 degree C. Txawm li cas los xij, muaj cov peaks me me superimposed mus rau qhov sib txawv ntawm cov diffuse peaks, raws li qhia hauv daim duab 2. Qhov no qhia tau hais tias cov coatings no tau dhau los ntawm qhov sib txawv ntawm crystallization. Daim duab 3 qhia txog kev sib raug zoo ntawm hardness thiab kub kho kub ntawm npib tsib xee phosphorus alloy coatings tom qab 30 vib nas this ntawm kev kho cua sov ntawm qhov sib txawv kub. Raws li pom nyob rau hauv daim duab 3, nyob rau hauv ib tug luv luv-term tshav kub kev kho mob tej yam kev mob, lub hardness ntawm cov npib tsib xee phosphorus alloy txheej nce nrog rau qhov nce ntawm kev kho cua sov kub. Ntawm 700 degree, hardness ncav cuag nws qhov siab tshaj plaws tus nqi; Raws li qhov kub thiab txias ntxiv, qhov hardness tiag tiag txo. Qhov tshwm sim no txawv txawv ntawm qhov tshwm sim ntawm kev kho cua sov (1 teev) qhia qhov siab tshaj plaws hardness ntawm 400 degree. Kev nce hauv hardness ntawm npib tsib xee phosphorus alloy txheej los ntawm nag lossis daus ntawm Ni3P nyuaj theem hauv txheej, thiab cov nag lossis daus ntawm Ni3P nyuaj theem nyob ntawm qib ntawm crystallization lossis atomic diffusion rearrangement ntawm txheej, nrog rau qhov loj me me. thiab dispersion degree ntawm Ni3P nag lossis daus theem. Tuav lub txheej ntawm qhov kub thiab txias rau qee lub sijhawm muab qee lub zog rau atomic diffusion rearrangement, yog li ua rau cov txheej txheem hloov pauv ntawm amorphous mus rau crystalline. Lub ncov pom ntawm X-ray diffraction spectrum nyob rau hauv daim duab 2 tuaj yeem ua pov thawj tias cov txheej txheem tau ua tiav kev hloov kho atomic diffusion, thiab Ni3P theem precipitated thiab dispersed nyob rau hauv lub txheej, uas ua rau sib txawv degrees ntawm crystallization ntawm txheej. Pom tseeb, ntawm qhov kub thiab txias, atomic diffusion ceev nrawm dua, thiab qee qhov ntawm atomic diffusion rearrangement tuaj yeem tshwm sim nyob rau lub sijhawm luv luv, uas ua rau muaj kev txhim kho tseem ceeb hauv cov tawv tawv ntawm txheej tom qab kev kho cua sov ntawm 700 degree thiab 30 vib nas this. . Nrog rau qhov nce ntxiv ntawm qhov kub thiab txias, lub zog tsav ntawm crystallization tshav kub nce, uas ua rau cov nag lossis daus Ni3P theem hais tau yooj yim dua, Dispersity txo qis, thiab lub hardness ntawm txheej txo qis dua.
