A Method to Evaluate the Durability of Sucker Rod Pumps and to Reduce Corrosive Wear
(UDJG, 2011)
The paper presents experimental tests made in static and dynamic conditions in order to establish the wear laws for different materials’ couples at different medium temperatures and pressures. Some complex wear laws were ...
The Influence of the Thermomagnetic Treatments on the Nitrided Superficial Layers Evolution after Wear Process (III)
(UDJG, 2011)
Two types of steel grades were subjected to a nitriding thermo-chemical treatment after the thermo-magnetic treatments. The structural aspects of the superficial layers of these steels are studied after the friction process ...
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 ...
