Pehea e hopu ai i ka mānoanoa o ka chrome plating no ka pololei piston rod machining

Hoʻohana nui ʻia ke koʻokoʻo piston i kēia manawa i nā ʻoihana he nui, no ka mea ua hoʻohana nui ʻia ke koʻokoʻo piston, no laila ʻoi aku ka nui o ka poʻe no ka piston rod production material koho i ke koho ʻana i nā mea hana like ʻole, a laila kāna hana ʻana o ʻOkoʻa nō hoʻi ka hana a me nā hiʻohiʻona.

ʻO ke kila 45 # ke kila kila, he maikaʻi ke anuanu a me ka hana wela, nā waiwai mechanical, ikaika kiʻekiʻe.45 # kila i ka quenching me ka tempering mua, paakiki oi ma mua o HRC55 no ka pono, a ma hope o ka wela lapaʻau, a laila quenching hiki hiki HRC42-46, no laila, i ka precision piston koʻokoʻo i maikai mechanical waiwai a me ka paakiki.

ʻO 40Cr he kila kalapona kalapona, ma hope o ka mālama ʻana i ka wela kūpono, hiki iā ʻoe ke loaʻa ka paʻakikī maikaʻi, ka plasticity.A hiki iā ia ke loaʻa nā waiwai mechanical piha maikaʻi ma hope o ka hoʻomaʻamaʻa ʻana, maikaʻi ka hopena haʻahaʻa haʻahaʻa haʻahaʻa.Eia hou, ua kūpono kēia kila no ka cyanidation a me ke kiʻekiʻe pinepine quenching lapaʻau i hoʻohui i ka tempering.

ʻO ke kila GCr15 kahi ʻano o nā mea i hoʻopili ʻia me ka liʻiliʻi o ka carbon chromium e lawe ana i ke kila, me ka paʻakikī kiʻekiʻe, ma hope o ka mālama ʻana i ka wela ma hope o ka paʻakikī kiʻekiʻe.A i ka wā e hoʻopiʻi ʻia ai me ka mālama ʻana i ka wela haʻahaʻa, hiki ke loaʻa ka paʻakikī kiʻekiʻe, ka hoʻonohonoho like ʻana a me nā waiwai hoʻoluhi pili kiʻekiʻe me ka huhū brittleness.

ʻO ka Sus304 ke kūpaʻa corrosion kiʻekiʻe, hiki i ka haʻahaʻa haʻahaʻa, ka lumi wela a me ka wela kiʻekiʻe he plasticity kiʻekiʻe a me ka paʻakikī a ʻoi aku ka maikaʻi o ke anuanu a me ka weldability.No ka mea, ʻaʻohe hoʻololi ʻana o kāna austenite i ka wā e wela ai, ʻaʻole hiki ke hoʻoikaika ʻia nā koʻokoʻo piston pololei e ka mālama wela a hiki ke mālama ʻia i ka wela e hoʻoikaika i ke kūpaʻa ʻana o ke kila.

Pono e hoʻoholo ʻia ka mānoanoa chrome plating o ke kaʻina hana piston rod i hui pū me ka mea maoli.Ma ke kaʻina hoʻoheheʻe chrome piston rod, pili ka mānoanoa o ka papa chrome me ka paʻakikī o ka ʻili.Ke hoʻokō ʻia ka chrome plating, hiki ke hoʻoholo ʻia e like me nā koi o ka mea kūʻai aku i mea e hoʻokō ai i kahi hana maikaʻi.
