Abstract

The issue of crystallization during the laser cladding process poses a significant challenge to the application of amorphous coatings. In order to explore the practical application of Fe_41.5Co_12.2Cr_7.4Mo_37.3C_0.3B_0.5Y_0.4Al_0.4 (at.%) amorphous composite coatings, this study fabricated coatings with different scanning speeds. The aim was to delve into their crystallization processes and assess the consequential effects on the coatings’ properties. The study revealed that crystallization predominantly occurs in the coatings’ overlapping region, which can be divided into two zones: the overlapping transition zone (OTZ) and the overlapping heat affected zone (OHAZ). The crystallization extent within the OHAZ is higher than in the OTZ, attributable to the disparate cooling rates characteristic of each region. With increasing scanning speed, the OHAZ gradually increases and the OTZ decreases. The coating prepared at 2000 mm/min has excellent corrosion resistance (polarization resistance 10,814.2 Ω $\cdot$ cm²) and wear resistance (wear rate (8.88 $\pm$ 0.378) $\times$ 10^–6 mm³/N $\cdot$ m).

重叠区域的微观结构对激光包覆铁基非晶复合涂层耐磨/耐腐蚀性能的影响

激光熔覆过程中的结晶问题给非晶涂层的应用带来了巨大挑战。为了探索 Fe41.5Co12.2Cr7.4Mo37.3C0.3B0.5Y0.4Al0.4（at.%）非晶复合涂层的实际应用，本研究采用不同的扫描速度制作涂层。目的是深入研究其结晶过程，并评估其对涂层性能的影响。研究发现，结晶主要发生在涂层的重叠区，重叠区可分为两个区域：重叠过渡区（OTZ）和重叠热影响区（OHAZ）。OHAZ 内的结晶程度高于 OTZ，这是因为每个区域的冷却速度不同。随着扫描速度的增加，OHAZ 逐渐增大，OTZ 逐渐减小。以 2000 mm/min 的速度制备的涂层具有优异的耐腐蚀性（极化电阻为 10,814.2 Ω-cm2）和耐磨性（磨损率为 (8.88±0.378)×10-6 mm3/N-m）。

期刊介绍： The Journal of Non-Crystalline Solids publishes review articles, research papers, and Letters to the Editor on amorphous and glassy materials, including inorganic, organic, polymeric, hybrid and metallic systems. Papers on partially glassy materials, such as glass-ceramics and glass-matrix composites, and papers involving the liquid state are also included in so far as the properties of the liquid are relevant for the formation of the solid. In all cases the papers must demonstrate both novelty and importance to the field, by way of significant advances in understanding or application of non-crystalline solids; in the case of Letters, a compelling case must also be made for expedited handling.
