▎ 摘　　要

NOVELTY - Growing of graphene sensor matrix in situ on cemented carbide comprises adopting medium frequency magnetron sputtering to deposit amorphous silicon carbide film on surface of cemented carbide; and performing vacuum annealing to grow graphene sensor matrix required for space drilling in situ in cemented carbide surface. USE - Growing of graphene sensor matrix in situ on cemented carbide. ADVANTAGE - The method is capable of space drilling on cemented carbide surface and overcomes defect of existing sensor with low sensitivity, has short service life and can be easily attenuated.
