Wear-resistant laser cladding

At laser deposition welding with powder, the laser heats the work piece and melts it locally. Simultaneously, an inert gas is mixed with the fine metal powder is added to the process. Operating area supply with the metal/gas mixture takes place via off-axial or coaxial nozzles. The metal powder melts on the heated spot and binds with the work piece metal. The process is applied everywhere expensive components have to be sealed and repaired. In addition to forming tools, engine components and turbine components like blades are considered the most well-known repair parts. The procedure is used with the build up of function layers, like wear protection layer.

YC30熔覆頭─基礎裝備
對較少件數進行低成本加工

對比賽用自行車的剎車碟來說,它的優勢在於當發生非常有限的局部熱輸入時,可以避免熱翹曲。這個結構精細、敏感的功能區域是用3D雷射硬化的。

為輥子加上耐磨的雷射熔覆

在鋼鐵工業的軋鋼機中,需要使用長度為0.5公尺至2公尺的不同的輥子。身為全球最大的鋼鐵生產商,Tata Steel依賴雷射熔覆技術。在三班連續運行作業的情況下,原本僅有8天使用壽命的輥子,藉由耐磨塗層可以將使用壽命提高十倍以上。

木材工業中的砍刀
由於新的硬度和耐磨功能的熔覆,木材工業中重負荷的砍刀刀口在磨損後之後,可以局部性地進行強化處理。這大大節省了成本,因為修理僅限於受損或已使用的區域。藉由雷射熔覆,熔覆的厚度可選擇0.1mm至1.5mm,寬度可以在1mm至5mm之間調整。較厚的熔覆需要將多個塗層交疊在一起。
