This book introduces the applications of laser in surface modification, such as laser cladding of Stellite alloys and metal-ceramic composites. Besides, nanomaterials including carbon nanotubes and Al2O3 nanoparticles are brought into the laser processing, to form high-temperature resistance, chemical stability, and wear- and oxidation-resistant composite coatings. The readers will get more knowledge about the basic principle and application of laser cladding and laser surface hardening technologies, and gain a deep insight into the process and characteristics of the nanomaterial-assisted laser surface enhancement. It provides references for the researchers, engineers, and students in the fields of mechanical engineering, laser processing, and material engineering.

Two typical hybrid laser surface modification processes, i.e. electro/magnetic field aided laser process and supersonic laser deposition technology, are introduced in the book, to solve the common problems in quality control and low efficiency of the laser-only surface modification technology, high contamination and high consumption of the traditional surface modification technology. This book focuses on the principle, characteristics, special equipment, process and industrial applications of the hybrid laser surface modification processes based on the recent research results of the author’s group, and provides theoretical guidance and engineering reference for the researchers and engineers engaging in the field of surface engineering and manufacturing.

Knowledge Workers in Contemporary China: Reform, and Resistance in the Publishing Industry concentrates on the trajectories of the labor process transformation of knowledge workers, mainly editors, in the Chinese publishing industry. The book focuses on their changing social, economic, and political roles, their dilemma, challenges, and opportunities associated with current social reform, and China’s integration into the global political economy. At its core, the book addresses three different yet interrelated processes of the political economy of communication: commodification, structuration, and spatialization in the Chinese publishing industry. It examines whether worker organizations and trade unions are effective in presenting editors’ legitimate rights and interests in current publishing reform. Through the political economic analysis of knowledge workers in China’s publishing industry, particularly editors, Jianhua Yao attempts to help readers better understand the broader social and economic transformations, specifically the network of power relations and institutional contexts in which Chinese editors are situated, that have been taking place in China since the late 1970s.
