Ndeipi mhedzisiro yealloying zvinhu paaluminium bronze

Mhedzisiro yealloying element paaluminium bronzezviri sezvinotevera:

Iron Fe:

1. Simbi yakawandisa mualloy inokonzeresa tsono-yakafanana neFeAl3 makomisheni munyama, zvichikonzera kushanduka kwemaitiro emagetsi uye kuderera kwekusagadzikana kwekuora;

2. Simbi inononoka kupararira kwemaatomu mualuminium bronze uye inowedzera kugadzikana kwedobech. Imwe simbi shoma inogona kudzivisa "self-annealing" chiitiko che brittleness yealuminium bronze, zvakanyanya kuderedza brittleness yealloy, uye kuwedzera 0.5-1% zvinyorwa zvinoita kuti zviyo zvive zvakanaka.

Manganese Mn:

1. Kupisa kunoputika kwekuputika kunogona kuderedzwa nekuwedzera 0.3-0.5% manganese kune binary aluminium bronze;

2. Kana imwe simbi yakawedzerwa mu manganese-aluminium bronze, simbi inogona kunatsa zviyo, uye kune zvimedu zvakanaka zveFe-aluminium zvinosanganiswa mu microstructure, iyo inovandudza maitiro emagetsi uye kupfeka kusagadzikana, asi inoderedza simba re manganese pane dobech stabilization.

Tin Sn:

1. Hapana kupfuura 0.2% tin ichachinja corrosion resistance ye-single-phase aruminiyamu bronze muutsi uye acidic zvishoma.

Chromium Cr:

1. Chikamu chidiki chechromium chakawedzerwa kune binary aruminiyamu bronze chinobatsira,

2. Kudzivisa iyo alloy annealing kupisa zviyo kukura, uye zvakanyanya kunatsiridza kuoma kwealloy mushure mekuvhara.

3. Alloying zvinhu zvinokanganisa zvinhu zvendarira chena

Zinc Zn:

1. Yakawanda yakanyungudika mumhangura-nickel alloy, tamba basa rekusimbisa mhinduro yakasimba, inovandudza simba uye kuoma, kuwedzera kusimba kwekuora.

Kazhinji, zvinhu zvisingawanzo kunyungudika nemhangura, asi chidimbu chidiki chesimbi dzepasi, ingave yakawedzerwa imwe kana muchimiro chevhu rakasanganiswa isingawanzo, zvinobatsira kune michina yemhangura, uye haina mhedzisiro pamagetsi conductivity yemhangura. Zvinhu zvakadaro zvinogona kuumba maumbirwo akanyanya kunyungudika netsvina senge lead uye bismuth mumhangura, achigadzira akatsetseka spherical particles akagoverwa muzviyo, kunatsa zviyo uye kunatsiridza tembiricha yepurasitiki yemhangura. Mune mamwe mazwi, kureba uye shrinkage yeCu alloy pa800 yakawedzera zvakanyanya nekuwedzera kweiyo cerium content.
