![]() ![]() ![]() Ultimately, this means a higher likelihood of coating failure and shorter service life. But together with the currently used materials (nickel- and ferrous-based alloys in combination with nickel-based bond coats), this results in relatively low coating adhesive and cohesive strengths, limiting the coating thickness capabilities. ![]() To date, the most widely established process for this is electric arc wire spray (EAW). Components require thermal spray coatings to reclaim dimension, after applying new material over the required finish size dimension, the cylinders and decks must be machined to the final stack dimension. During this process, parent material is removed, and the stacking height of the engine is changed and seals can be impaired. But corrosion and vibratory wear degrades their surfaces, so that these components need to be machined periodically. Engine blocks and cylinder heads are the core of any mining equipment engine. ![]()
