Thermal barrier coatings are widely used as surface modifications to enhance the surface properties of the material and protect from surface degradations such as erosion and corrosion. Ceramic-based coatings are highly recommended to increase wear resistance in the industrial sector. In this paper, an alumina-titania ceramic powder was deposited on an aluminum alloy using an atmospheric plasma spray technique. Experimental investigations were performed to study the behavior and erosion rate of the material. Solid particle erosion studies were performed by varying the particle velocity and particle flow rate. The angle impingement and stand-off distance were constant for comparison. The base metal has a clinging effect and the mass change was negative at a maximum particle flow rate of 4 g·min⁻¹. Under the same process conditions, the coated sample had a reduced lifetime and reached a maximum erosion rate of 0.052 (Δg/g). The solid particle erosion studies confirmed that the base metal aluminum alloy had severe surface damage with erodent reinforcement when compared to the coated samples. The influence of the particle velocity, particle flow rate, and input process parameters were also identified.

热障涂层被广泛用作表面改性，以增强材料的表面性能并防止表面退化，例如侵蚀和腐蚀。强烈建议使用陶瓷基涂层来提高工业领域的耐磨性。在本文中，使用大气等离子喷涂技术将氧化铝-二氧化钛陶瓷粉末沉积在铝合金上。进行了实验研究以研究材料的行为和侵蚀率。通过改变颗粒速度和颗粒流速来进行固体颗粒侵蚀研究。为了比较，角度撞击和间隔距离是恒定的。母材具有粘着作用，在最大颗粒流速为 4 g·min ^{-1 时}质量变化为负. 在相同的工艺条件下，涂层样品的寿命缩短，最大侵蚀率为 0.052 (Δ g/g )。固体颗粒侵蚀研究证实，与涂层样品相比，贱金属铝合金具有严重的表面损伤和侵蚀增强。还确定了粒子速度、粒子流速和输入工艺参数的影响。
