Hardware arung arai ni gaw, dai ni na aten na hpaga lam hte shani shagu gram lajang ai lam ni a matu ra kadawn ai arung arai ni hku nna, arung arai ni hpe shingdaw ai lam hte galaw shapraw ai ladat amyu myu ra nga ai. Hardware arung arai ni hpe shingdaw ai lam gaw, madung hku nna, n-gun ja ai, n-gun ja ai, n-gun ja ai hpe bu hpun na matu, asak galu na matu, n-gun rawng ai arung arai ni, alloy ratios, heat treatment galaw ai ladat ni, hte npu na tsi ladat ni hpe lata ai lam hta madung tawn ai. Ndai laika hta hardware arung arai ni a matu madung synthesis ladat ni hte madung ladat ni hpe hkrak hkrak tsun dan na re.
1. Metal arung arai ni hpe lata la nna tsi lajang ai lam
Hardware arung arai ni hpe hpaw shabawn ai gaw madung hku nna base metal arung arai ni hpe lata ai hta madung nga ai. Common hardware arung arai ni hta carbon n-gang, alloy n-gang, n-gang n-gang, hte n-gun n-rawng ai n-gang ni lawm ai (copper, aluminum, shanhte a alloy zawn re ai) ni lawm ai. Carbon steel gaw, manu n law ai hte galaw shapraw na matu loi ai majaw, wrenches hte screwdrivers zawn re ai arung arai ni hta grai lang ma ai. Grai yak ai, n-gun ja ai n-gun n-gun n-gun n-gun n-gun n-gun ni (chrome-vandium n-gang zawn re ai n-gang hte tsaw ai{6}}speed steel zawn re ai) hpe drill bits zawn re ai tsaw ai{7}}load arung arai ni hpe galaw shapraw ai hta lang ai.
N-gun n rawng shi yang, magri arung arai ni gaw, n-gun n rawng ai, n-gun n rawng ai, shawng nnan na shat sha ai lam ni lawm ai, shawng nnan tsi lajang ai lam ni hpe galaw ai. Hka lim ai aten hta, carbon, manganese, chromium zawn re ai element ni a ratio hpe atsawm sha hkang ra ai majaw, dai arai a jak rung atsam ni hpe grau kaja hkra galaw ra ai. Casting galaw ngut ai hpang, dai metal billet gaw shi a kata na hkrang hpe gram lajang na matu hte shi a n-gun atsam hte ngang kang ai lam hpe grau kaja hkra galaw na matu, n-gun jaw ai (sh) shingjawng ai lam ni hpe hkrum sha nga ai.
2. Tsi lajang ai lam ni hpe n-gun jaw nna, katsi ai lam ni
Alloying gaw hardware arung arai ni a bungli hpe grau kaja hkra galaw na matu ahkyak ai lahkam langai rai nga ai. Ga shadawn, chromium (Cr), vanedium (V), hte molybdenum (Mo) zawn re ai lam ni hpe carbon n-gang hta jat bang ai gaw, shi a ngang kang ai lam, n-gun n-gun hpe ninghkap lu ai atsam, thermal stability hpe grai jat ya ai. High{2}}speed steel (W18Cr4V zawn re ai), tungsten (W), chromium (Cr), vanedium (V) hpe bang ai majaw, n-gun kaba ai-}sped cutting tools ni hpe galaw shapraw na matu htuk manu ai.
Heat treatment gaw hardware arung arai ni hpe galaw shapraw ai hta madung lahkam langai rai nna, madung hku nna htum mat ai, myit npyaw ai, annealing ni lawm ai. Quenching gaw lawan ai hku katsi ai hku nna, arung arai a n-gun hpe jat ya ai, raitim, ndai gaw n-gun n rawng ai lam hpe jat wa shangun lu ai, hpang na myit masin hpe n-gun ja ai hte ngang kang ai lam hpe rap ra hkra galaw ra ai. Annealing gaw dai arai a n-gun hpe shayawm ya nna, shi a machinability hpe grau kaja hkra galaw ya ai. Ga shadawn, tsaw ai-carbon n-gang arung arai ni gaw, kaja dik ai hkrang shapraw ai lam hpe lu la na matu, hpaw hpang ai hpang, n-gun n law ai wa hpe n-gun n rawng ai sha, n-gun n rawng ai wa a n-gun yawm ai lam hpe hkam sha ra ai.
3. Hpaji hpe gawgap nna galaw sa wa ai lam
Hardware arung arai ni hpe galaw na matu madung ladat ni gaw, hkai lu hkai sha ai, masat da ai, dazik shakap ai, hte n-gun jaw ai lam ni lawm ai. Forging gaw tsaw ai{1}} n-gun rawng ai arung arai ni hpe galaw na matu htuk manu ai (hka n-gang hte pliers zawn re ai). High{3}} hpe n-gun jaw ai gaw, magri mam hpe gram lajang ya nna, jak rung atsam ni hpe grau kaja hkra galaw ya ai. Casting hpe n-gun ja ai hkrang ni nga ai arung arai ni a matu lang ai (wrenches (sh) mold nkau mi zawn re ai), raitim, law law lang gaw, hkrak ai lam hpe grau kaja hkra galaw na matu, hpang na machining ra ai.
Machining (galai shai ai, htu ai, grinding zawn re ai) gaw hardware arung arai ni hpe ngut kre hkra galaw na matu ahkyak ai lahkam langai rai nga ai. Ga shadawn, drill bit a cutting edge gaw, n-gun ja ai hte ngang grin ai hpe lu la na matu, hkrak hkrak grin nga ra ai. Dai hta n-ga, CNC machining hpaji masa hpe jai lang ai gaw, yak hkak ai geometries ni hte arung arai ni hpe atsawm sha galaw lu shangun ai (ga shadawn, hkrak hkrak n-gun n-gun hte laksan{2}}shaped screwdrivers zawn re ai).
4. Ntsawm tsi lajang ai lam hte hkrang bung sumla ni
Surface tsi ladat gaw, hardware arung arai ni a n-gun hpe ninghkap lu ai atsam, n-gun n-gun hpe ninghkap lu ai atsam, hte daw jau ai prat hpe jat ya lu na matu ahkyak nga ai. Masha law malawng lang ai tsi ladat ni hta, wan n-gun (galvanizing hte chromium plating zawn re ai), carburizing, nitriding ni lawm ai. Wan n-gun gaw, n-gun n rawng ai hpe makawp maga na matu, tool ntsa kaw makawp maga ai layer hpe hpaw ya nna, carburizing hte nitriding gaw, chemical heat hpe tsi lajang ai hku nna, ntsa lam n-gun hpe jat ya ai.
Kade nna ai aten hta, coating hpaji ni (TiN hte TiAlN coatings zawn re ai) ni hpe, n-gun kaba ai-end hardware arung arai ni hta grai lang wa sai. Ndai superhard coatings ni gaw, tool cutting galaw ai lam hte n-gun hpe ninghkap lu ai atsam hpe grai kaja hkra galaw ya lu ai, tool prat hpe jat ya lu ai. Ga shadawn, coated drill bits ni gaw, n-gun rawng ai drill bits ni hta grau nna, metalworking hta grau nna akyu rawng ai.
5. Dawdan ai lam
Hardware arung arai ni hpe shingdaw ai lam gaw, arung arai hpaji, katsi ai hpe tsi lajang ai hpaji masa, machining, hte npu na engineering ni lawm ai hpaji amyu myu hte seng ai ladat langai rai nga ai. Rational material lata ai lam, alloy hkrang shapraw ai lam, hkrak tup ai nbung hpe tsi lajang ai lam, grau tsaw ai ntsa tsi ladat ni hku nna, n-gun ja ai{1}}}performance hte kam hpa mai ai hardware arung arai ni hpe galaw shapraw lu ai. Htawm hpang de, arung arai nnan ni (powder metallurgy high{3}speed steel hte composite arung arai ni zawn re ai) hte hpaji rawng ai galaw shapraw ai hpaji masa ni hpe gyin shalat ai hte, hardware arung arai ni hpe hpaw shabawn ai ladat hpe grau tsaw ai hpaga lam madang ni a ra sharawng ai lam ni hpe hkan sa na matu grau nna kaja hkra galaw na re.
