摘要:

鐵基非晶合金因為優(yōu)異的力學(xué)、化學(xué)和物理性能，以及較低的成本，在工業(yè)上非常有應(yīng)用前景。但鐵基非晶合金韌性和塑性欠缺，一直制約著其在涂層應(yīng)用領(lǐng)域的發(fā)展。為解決這個問題，研究學(xué)者們在激光熔覆制備工藝和材料成分方面進(jìn)行了大量了研究，以探究非晶相和晶體相雙相共存增塑增韌的作用機理，取得了豐碩的成果。非晶相和晶體相雙相共存能有效提高鐵基非晶合金復(fù)合涂層的韌性和塑性，晶體相的晶粒尺寸、結(jié)構(gòu)和分布情況都對鐵基非晶合金復(fù)合涂層的韌性或塑性有較大的影響。對近年來激光熔覆鐵基非晶合金復(fù)合涂層增塑增韌在激光工藝參數(shù)、材料成分和輔助方法方面的研究進(jìn)展進(jìn)行了歸納和總結(jié)，分析了目前存在的主要問題，并展望了未來的發(fā)展方向。

Abstract:

Fe-based amorphous alloys are promising for industrial applications because of their excellent mechanical, chemical and physical properties and low cost.However, the development of Fe-based amorphous alloys in the field of coating applications has been restricted by the lack of toughness and plasticity.To address this issue, researchers have conducted extensive studies on laser cladding preparation processes and elemental formulations to investigate the mechanism of plasticizing and toughening effects of amorphous and crystalline dual-phase coexistence, yielding fruitful results. Scholars have pointed out that the coexistence of amorphous phase and crystalline phase can effectively improve the toughness or plasticity of Fe�瞓ased amorphous alloy composite coating. The grain size, structure and distribution of crystalline phase have a great influence on the toughness or plasticity of Fe-based amorphous alloy composite coating.In this paper, the research progress of laser cladding iron based amorphous alloy composite coating plasticizing and toughening is summarized in terms of laser process parameters, element formulation and auxiliary methods in recent years.The main existing problems are analyzed, and the future development direction is forecasted.
