托輥密封件的高能束熱處理:是局部表面改性技術。采用的熱源有激光、電子束、離子束、電火花、超高頻感應沖擊、太陽能和同步輻射等。提高工件的疲勞強度。
High energy beam heat treatment of roller seals is a local surface modification technology. The heat sources used include laser, electron beam, ion beam, electric spark, ultra-high frequency induction shock, solar energy and synchrotron radiation. Improve the fatigue strength of the workpiece.
一.高能束加熱屬非接觸加熱。熱影響區極小州苗木 保定通風管道 絲網立柱模具 尼龍輸送帶 保定空壓機 高碑店養老院；高能束的加熱和冷卻速度很快，熱應力很小，因此工件變形小。奧氏體長大及碳原子和合金原子的擴散受到抑制，
1、 High energy beam heating belongs to non-contact heating. The Heat-affected zone is very small; The heating and cooling speed of high-energy beams is very fast, and the thermal stress is very small, so the deformation of the workpiece is small. Austenite growth and diffusion of carbon and alloy atoms are inhibited,
二.由于加熱速度快?？色@得細化和超細化組織的概況。由于高能束作用面積小，
2、 Due to the fast heating speed. An overview of refined and ultra refined organizations can be obtained. Due to the small interaction area of high-energy beams,
三.高能束熱處置懲罰靠工件自身冷卻淬火。金屬自己的熱容量足以使被處理的概況驟冷，保證完成馬氏體轉變，并能獲得隱晶馬氏體。急冷還可抑制碳化物的析出，從而減少脆性相的影響。
3、 The punishment for high-energy beam heat treatment relies on the workpiece's own cooling and quenching. The heat capacity of the metal itself is enough to quench the treated profile, ensure the completion of martensite transformation, and obtain cryptocrystalline martensite. Quenching can also suppress the precipitation of carbides, thereby reducing the impact of brittle phases.
四.高能束熱處理在金屬概況發生殘存壓應力。因而加熱速度快、冷卻速度亦快，
4、 High energy beam heat treatment causes residual compressive stress in the metal profile. Therefore, the heating speed is fast and the cooling speed is also fast,
五功率密度高、作用時間短。其過熱度和過冷度大于慣例熱處理，處置懲罰后概況硬度比慣例處置懲罰高5~10HRC沒有機械應力作用；高能束的束斑小
High power density and short action time. Its superheat and undercooling are greater than those of conventional heat treatment, and the overall hardness after treatment is 5-10HRC higher than that of conventional treatment without mechanical stress effect; Small beam spot of high-energy beam
