Research on Metal Parts Hardening by Superficial Alloying in Liquid and Solid State

Abstract

This paper presents the research results on the manufacture of some metal parts through the hardening process in liquid and solid state. This is a new, efficient and easily industrially adaptable process. It was experimented in Romania and abroad, with many positive results as compared to the usual technological processes.

Alternative for the Use of Sewage Sludge in Romania

“…Macro and micro levels tend to optimize and streamline all processes with minimal impact on the environment [5,18,20,22,24,[29][30][31][32][33][34][35][36][37]]. An ambitious package of measures was adopted by the European Commission on 2 December of 2015 regarding the circular economy.…”

Research on the Mechanical Characteristics of a Microalloyed Steel with V in the Agreement with Environmental Trends

“…These catalysts, together with other vanadium waste are subject processing by recycling [14,29]. Steels microalloyed with V are used for metal structures: containers, bridges, equipment for constructions [15,16,18,19].…”
