Addition of Chromium and its effect on the microstructure and mechanical properties of laser-coated high carbon ferrochrome alloy on mild steel

Laser cladding is an additive manufacturing technology that can be utilized in surface strengthening, modification, and repair of components that are subjected to adverse working conditions. This can be accomplished by the addition of functionally graded material with a remarkable limit to enhancing an engaged credited property of monolithic material that is superior and better than its monolithic counterparts. Chromium addition to the microstructure of components has been found to increase the electrochemical stability, high-temperature strength and corrosion resistance of laser additive manufactured components. The current study investigates the effect of the extra addition of chromium on the hardness and microstructure of laser coated high carbon ferrochrome FeCrV15 on steel baseplate.

Analysis of Factors Affecting Carbon Content Detection of Ferrochrome Alloy Using LIPS Method

Metal smelting process all kinds of element content directly influence the metal performance index and smelting process control .The amount of carbon become mainly alloy index for divided type and number. LIPS using high power laser ablation material produce plasma, in plasma radiation spectrum analysis; it could be used in the composition of solid, liquid and gas composition and concentration measurement. But the results of the measurement will be affected by some factors, this article through some experiments, that show the Influence factors for the measured results such as the delay time，the different environment of gas and the laser pulse energy and analyzed them.
