Abstract

Purpose

This paper aims to investigate the tribology, corrosion resistance and biocompatibility of high-temperature gas-nitrided Ti6Al4V alloy.

Design/methodology/approach

The tribological properties were studied by reciprocating wear tester. The corrosion resistance was evaluated by using potentiodynamic polarization test. The purified mouse leukaemic monocyte macrophage cells are used to investigate the biocompatibility.

Findings

The results show that the nitriding treatment leads to a significant improvement in the hardness and tribological properties of Ti6Al4V alloy. Specifically, compared to untreated Ti6Al4V, the hardness increases from 3.24 to 9.02 GPa, while the wear rate reduces by 12.5 times in sliding against a Ti6Al4V cylinder and 19.6 times in sliding against a Si3N4 ball. Furthermore, the nitriding treatment yields an improved corrosion resistance and a biocompatibility similar to that of untreated Ti6Al4V.

Originality/value

The nitrided Ti6Al4V alloy is an ideal material for the fabrication of load-bearing artificial implants.

Abstract

Purpose

Although domestic research on Chinese management is emerging, a suitable domestic theory is still needed to support and explain Chinese management practice. Given that, this paper aims to extract ideas of cultivation from Confucianism and propose a theoretical framework of self-cultivation with a purpose to provide new explanations for domestic (nondomestic as well) management practice.

Design/methodology/approach

Drawing from pre-Qin cultivation discourse and management practice, this paper develops a theoretical framework of self-cultivation and discusses its implications.

Findings

This paper argues that self-cultivation emphasizes self-consciousness, initiative and selflessness. It also includes self-reflection, self-discipline, self-study and self-improvement, as well as self-dedication, all of which reflect the ideal realm of “self-cultivation.” This “realm” refers to the process of pursuing an ideal personality and high moral standards.

Originality/value

This paper contributes to the literature by identifying various potential applications of self-cultivation theory to domestic research on organizational behavior in China.
