Follow through the sequence of steps to determine the best surface engineering
options for your component. To help, you may find it useful to make a
list of the factors relevant to your
application; it will help in subsequent analysis of the problem.
Which of the categories below best describes your component and its
function?
| Type of component |
Examples |
Select here |
| A structural part chosen for its strength or for containment
|
Pipes, pump bodies, valve bodies, casings, housings,
supports, rigs and similar structures, tanks. |
Structural Parts
|
| A part in static contact with another engineering component,
particularly with vibration or small motions present |
Heat exchangers, spacers, splines, couplings, dowels,
fasteners, seats, bearing housings, chains, wire ropes, pulleys |
Static Contact with
Vibration |
| A part in static contact with a product, either being
moulded, cured, cooked or fabricated |
Plastic and glass mouldings, food handling, baking,
die casting |
Static Contact with a Product
|
| A part which undergoes sliding or rolling contact against
another engineering component, or against a metallic product |
Shafts, journals, pistons and rings, cams, bearings,
pads, gears, seals, slideways. Also, metal cutting, drawing and forming
|
Sliding or Rolling Contact
with another component |
| A part which handles or slides against a product under
relatively light loads, specifically when that product may be abrasive
|
Textiles, paper and printing, filled plastics, leather,
wheat, soya and other base foodstuffs, pharmaceuticals, brakes, clutches
|
Low Load Sliding Contact
with an abrasive product |
| A part which handles or slides against a product under
highly loaded or impacting conditions, specifically when that product
may be abrasive or erosive |
Coal chutes, mining conveyors, diggers, crushers, millers,
extruders, cutters, compactors, and erosive situations like turbines,
impellers and pipework |
High Load Sliding or
Erosion with an abrasive product |
| A part which is in sliding or rolling contact with
another engineering component in the presence of a product, specifically
if that product may be abrasive and/or corrosive |
Pumps, mechanical seals, valves, slurry handling |
Contact with an engineering component in the presence
of an Abrasive and Corrosive
product or environment |
