Kufotokozera
Kuti mupange zomaliza zapamwamba pamtengo wotsika kwambiri komanso zodalirika, muyenera kusankha zida zovala zomwe zimakongoletsedwa ndi pulogalamu yanu yophwanya. Mfundo zazikuluzikulu zomwe muyenera kuziganizira motere:
1. Mtundu wa miyala kapena mchere woti uphwanyidwe.
2. Kukula kwa tinthu tating'onoting'ono, chinyezi ndi kalasi ya Mohs kuuma.
3. Zida ndi moyo wazitsulo zowombera zomwe zimagwiritsidwa ntchito kale.
Nthawi zambiri, kukana kuvala (kapena kuuma) kwa zida zomangira zitsulo zokhala ndi khoma kudzachepetsa kukana kwake (kapena kulimba). Njira yophatikizira mbiya muzinthu zachitsulo zamatrix imatha kukulitsa kukana kwake popanda kukhudza kukana kwake.
Chitsulo chachikulu cha Manganese
Chitsulo chapamwamba cha manganese ndi chinthu chosamva kuvala cha mbiri yakale ndipo chakhala chikugwiritsidwa ntchito kwambiri pophwanya mphamvu. Chitsulo chokwera cha manganese chimakhala ndi mphamvu yokana kwambiri. Kukaniza kuvala nthawi zambiri kumakhudzana ndi kupanikizika ndi kukhudzidwa kwake. Mukakhudzidwa kwambiri, mawonekedwe a austenite pamtunda amatha kuumitsa mpaka HRC50 kapena kupitilira apo.
Nyundo zapamwamba zachitsulo za manganese nthawi zambiri zimangolimbikitsidwa kuti ziphwanyidwe ndi zinthu zakukula kwa tinthu tating'ono komanso kulimba kochepa.

Chitsulo cha Martensitic
Mapangidwe a Martensite amapangidwa ndi kuzizira kofulumira kwa chitsulo chodzaza mpweya. Ma atomu a carbon amatha kufalikira kuchokera ku martensite pokhapokha pozizira mofulumira pambuyo pa kutentha. Chitsulo cha Martensitic chimakhala cholimba kwambiri kuposa chitsulo chapamwamba cha manganese, koma kukana kwake kumachepanso. Kuuma kwachitsulo cha martensitic kuli pakati pa HRC46-56. Kutengera ndi zinthuzi, martensitic steel blow bar nthawi zambiri amalimbikitsidwa kuti aphwanye ntchito zomwe zimakhala zochepa koma kukana kwamphamvu kumafunikira.

High Chromium White Iron
Mu chitsulo choyera cha chromium, mpweya umaphatikizidwa ndi chromium mu mawonekedwe a chromium carbide. Chitsulo choyera cha chromium chimakhala cholimba kwambiri. Pambuyo pa chithandizo cha kutentha, kuuma kwake kumatha kufika 60-64HRC, koma kukana kwake kumachepetsedwa. Poyerekeza ndi chitsulo chochuluka cha manganese ndi chitsulo cha martensitic, chitsulo chokwera kwambiri cha chromium chimakhala ndi kukana kwamphamvu kwambiri, koma kukana kwake ndikotsika kwambiri.

Ceramic-Metal Composite Material (CMC)
CMC ndi chinthu chosamva kuvala chomwe chimaphatikiza kulimba kwazitsulo zachitsulo (chitsulo chamartensitic kapena chitsulo chachitsulo cha chromium chapamwamba) ndi kuuma kwambiri kwa mafakitale a ceramic. Tinthu tating'ono tating'ono tating'ono tating'ono timapangidwa mwapadera kuti tipange porous thupi la ceramic particles. Chitsulo chosungunula chimalowa kwathunthu muzitsulo za ceramic poyatsira ndikuphatikizana bwino ndi mbiya.
Mapangidwe awa amatha kupititsa patsogolo magwiridwe antchito odana ndi kuvala a nkhope yogwira ntchito; panthawi imodzimodziyo, thupi lalikulu la nkhonya kapena nyundo likadali lopangidwa ndi chitsulo kuti liwonetsetse kuti likugwira ntchito bwino, kuthetsa bwino kutsutsana pakati pa kuvala kukana ndi kukana kukhudzidwa, ndipo kungasinthidwe kuzinthu zosiyanasiyana zogwirira ntchito. Zimatsegula gawo latsopano losankha zida zopangira zovala zapamwamba kwa ogwiritsa ntchito ambiri, ndikupanga phindu labwino pazachuma.
a.Martensitic Steel + Ceramic
Poyerekeza ndi bar wamba ya martensitic blower, nyundo ya martensitic ceramic blown imakhala yolimba kwambiri pamavalidwe ake, koma kukana kwa nyundo yowomba sikuchepa. M'malo ogwirira ntchito, bar ya martensitic ceramic blower imatha kukhala m'malo mwa pulogalamuyo ndipo nthawi zambiri imatha kupeza pafupifupi ka 2 kapena moyo wautali wautumiki.
b.High Chromium White Iron +Ceramic
Ngakhale chitsulo chowombera chapamwamba cha chromium chimakhala kale ndi kukana kwamphamvu kwambiri, mukaphwanya zida zolimba kwambiri, monga granite, mipiringidzo yosamva kuvala nthawi zambiri imagwiritsidwa ntchito kutalikitsa moyo wawo wogwira ntchito. Pamenepa, chitsulo chopangidwa ndi chromium chapamwamba chokhala ndi chitsulo choyikirapo cha ceramic ndi njira yabwinoko. Chifukwa cha kuyika kwa zida zadothi, kuuma kwa nyundo yowomba kumawonjezekanso, ndipo kukana kwake kumayenda bwino, nthawi zambiri 2 kapena moyo wautali wautumiki kuposa chitsulo choyera cha chromium.
Ubwino wa Ceramic-Metal Composite Material (CMC)
(1) Olimba koma osapunthwa, olimba komanso osamva kuvala, kukwaniritsa kulimba kwapawiri komanso kulimba kwambiri;
(2) Ceramic kuuma ndi 2100HV, ndi kuvala kukana akhoza kufika 3 mpaka 4 nthawi wamba aloyi zipangizo;
(3) Mapangidwe amunthu payekha, mzere wovala bwino;
(4) Moyo wautali wautumiki komanso phindu lalikulu lazachuma.
