Durability of the Layers Deposed with Metal – Ceramic Powders Type CR3 C2 –NICR and High Speed Flame (HVOF)
(UDJG, 2011)The durability of the reconditioned or preventively covered with powders type Cr3 C2 –NiCr product may outrun the performances of the original product and (the original specification, too). Due to the deposit of these ... -
Hardening of the Grey Cast Iron Through the Vibrating Electrode Method Using a WC Electrode and in Combination with Ti Electrode
(Universitatea "Dunărea de Jos" din Galaţi, 2008)There have been tested samples of grey cast iron, the hardening being made through WC coating through the vibrating electrode method with a layer, two layers and through double layers combined with Ti and TiC. Besides ... -
Influence of Some Technological Parametersof Fluidized Bed Carbonitriding on the Surface Hardness of Carbonitrided Parts from Low Allow Steels
(Universitatea "Dunărea de Jos" din Galați, 2016)The paper describes the experimental research of thermos-chemical treatment of carbonitriding performed on samples of different brands of low alloy steels. The technological parameters whose influence on the carbonitrided ... -
Physico-Mechanical Characteristics of Hard Alloys Made Out of Many Carbides
(Universitatea "Dunărea de Jos" din Galați, 2005)The Hard alloys of type WC-TiC-Co can be used to process materials with long chips, such as steels [1]. Titanium carbide or TiC-WC solid solutions, added as alloying constituents in the compositions of WC-Co pseudo-alloys ... -
Studies and Research on Treatment of Titanium Alloys
(Universitatea "Dunărea de Jos" din Galați, 2014)Titanium and its alloys have an extended use due to special properties. The paper highlights the TiZr alloy intended to manufacture prostheses, the influence of plastic deformation on the properties and structure. Applied ... -
The Influence of Polarization Tension of the Grading Over thin Layer Properties of TiN Deposed Through PDV Method
(Universitatea "Dunărea de Jos" din Galați, 2006)The deposits of tough thin layers on pieces and tools through PDV method knew a permanent and constant spreading owing to the great applicability of the resulting coatings which make that the thin layer deposit from the ... -
