钛
Titanium, a silver chemical element, finds wide industrial use in aerospace, automotive, and medical fields. It's often alloyed.
快速冷却
Fast cooling rapidly lowers temperature using a cooling medium like oil, water, brine, or pressurized gas.
工模具
（淬火/回火）
Tool steels undergo quenching and tempering for optimal mechanical properties, selected based on tool application and performance requirements.
铝化物涂层
Aluminizing diffuses aluminum into metals, creating corrosion-resistant layers, often applied to steels and superalloys.
淬火
Metals harden through thermal, mechanical, or precipitation methods, increasing lattice defects for enhanced hardness.
正火
Normalizing refines grain structure in ferrous alloys, retaining more hardness than annealing, commonly used after forging or casting.
钎焊
Vacuum brazing: strong, clean joints in an oxygen-free atmosphere. Ideal for aerospace and medical components.
退火
Annealing heats parts above their recrystallization temperature, increasing ductility and facilitating workability, preparing steel for subsequent heat treatment.
沉淀硬化
Precipitation hardening boosts yield strength in materials via heating, quenching, and aging, often applied to stainless steels and superalloys.
回火
Tempering reduces excess hardness after hardening, adjusting material hardness through specific temperature and duration parameters tailored to application.

常见问题
关于产品和工艺您需要了解的一切。
渗氮是一种热处理工艺，通过将氮扩散到材料表层来提高金属零件的表面硬度和耐磨性。通常是在高温下将零件置于富氮气氛中进行。
气体渗氮是在炉内高温下将零件置于含氨的富氮气氛中，而等离子渗氮则利用部分真空中的等离子放电产生氮离子，再使其扩散到零件表面。气体渗氮可实现更密集、更高效的装炉，而离子（等离子）渗氮则对单个零件具有良好的屏蔽能力。在等离子渗氮中，每个零件都需要装夹并具备导电性才能成功渗氮
氮碳共渗是一种表面硬化工艺，通过将氮和碳扩散到金属零件表层来提高硬度、耐磨性和耐腐蚀性。通常是在高温下将零件置于富含氮和碳的气氛中进行。由于其目标往往是在零件表面形成经过设计的“白亮层”，因此周期通常较短。
与传统气氛炉相比，真空炉具有多项优势，包括：
精确控制加热和冷却过程，实现均匀加热并将零件变形降至最低。
– 可实现更高的工艺温度，温度可超过 2500F (1371C)，炉内几乎无损耗或损耗极小。
-能够对特殊合金进行热处理，例如真空退火、真空钎焊和真空烧结。
-由于炉内工艺气氛中不含氧气，可消除零件的表面氧化物和脱碳。
-冷壁设计适用于“洁净”车间。加热始终采用电力。
气相渗铝 (VPA) 是一种为特殊镍基高温合金涡轮发动机叶片和部件进行涂层的工艺，可帮助其抵抗高温氧化腐蚀。Nitrex 高温马弗罐系统为这些高温合金的涂层提供了理想的环境。NiAl 层在极端工况下优先氧化，形成薄而致密的氧化铝膜。
渗氮、氮碳共渗和真空炉广泛应用于汽车、航空航天、工具、注塑成型和一般制造业等行业。这些工艺用于提高关键应用中金属零件的耐磨性、疲劳强度和耐腐蚀性。
