Increasing demand and resource overuse has prompted the exploration of spent secondary materials as a primary raw material for variety applications, leading to more sustainable environment. Spent electric grid ceramic insulator, one waste industry, good hardness strength. It can be reused value-added in Abrasive Water Jet Machining (AWJM) industry. The present work deals with generation cost-ef...

the plain carbon steel “ck45” has relatively well mechanical and metallurgical properties and low cost. the purpose of this research was the property evaluation of this steel on abrasive wear and impact for using in plows and other tillage tools. tillage tool should resist in abrasive wear and impact simultaneously. several heat treatments were done on specimens of this steel. a standard test d...

Abrasive wear limits the lifetime of many machine components. Most empirical models relate abrasive resistance to material hardness. In reality, however, other properties are also influencing as scratch abrasion damage follows from a highly complex stress trajectory upon scratching. Numerical (finite element) simulation requires use model, which translates this into degradation and removal. inc...

Abrasive waterjet cutting nowadays represents cold precise, computer controlled shape cutting without any strain [1, 2]. These attributes pose this technology to the position of permanent use in the future, that represents excellent perspective for expansion in volume sectors, especially there, where the materials with excellent utility properties are used [3, 4]. The AWJ technology is, under e...
