Which Metal Ceramic Or Hard Alloy Has Higher Wear Resistance?

Ceramic materials generally have higher wear resistance compared to hard alloys. This is due to their extreme hardness and ability to withstand abrasion. Ceramics are noted for having a much longer service life in comparison to even the hardest steels, with some ceramics outperforming steel by 10 to 20 times in terms of wear resistance .

However, it's important to note that ceramics, while being harder and more wear-resistant, are also more brittle than metal alloys. This brittleness can make them less suitable for applications where impact resistance and toughness are required .
