In this work. dense and pinhole-free poly-para-xylylene (PPX) with high thermal stability. high insulating property and high lubricity has been designed as coating layer for Fe-based amorphous powder. Three ultra-thin PPX layers have been successfully deposited on the surface of FeSiBPNbCr amorphous powder via chemical vapor deposition (CVD) polymerization. https://www.roneverhart.com/ASUS-VivoBook-X515-15-6-FHD-Laptop-Intel-Core-i5-1135G7-2-4-GHz-Intel-Iris-Xe-Graphics-16GB-DDR4-RAM-1TB-SSD-Windows-/
