表面淬火的 meaning in English

The research results on laser hardening of the fibre - cutting roller showed that using laser surface hardening process instead of thermal spraying to strengthen the surface of fibre - cutting roller of 4crl 3 stainless steel is practicable . not only this technique overcame the disadvantage of larger heat distortion by using thermal spraying but also possessed the advantages that the operation is simply and that expense is easy
过丝辊激光表面淬火的研究表明，选取恰当的工艺参数对过丝辊表面采用激光淬火替代传统的热喷涂是切实可行的，该方法不但能够克服热喷涂方法中工件变形大的不足，而且工艺简便、成本低廉，实用性强，具有明显的经济效益和推广应用价值。
