Ceramic Chipped UHMW - Need different material!
Ceramic Chipped UHMW - Need different material!
(OP)
I'm using a ceramic chipped filled UHMW for skids on my anyhdrous tool bar. I was told that they would outlast standard UHMW material in abrasion resistance, but after 500 acres in sandy/rocky soil, the skids are in need of replacement. I'm looking for a material that will outlast my current skid. The ideal material will be easily drilled/punched and have the ability to bend to the shape of the attach plate without stressing the skid. If at all possible, I need to be able to install this skid without heating it up to make it plyable. Dimensions are 1/4" thick, 4.5" wide, 19" long, with a large radius 45 degree bend in the middle. Any suggestions will help! Thank you!





RE: Ceramic Chipped UHMW - Need different material!
A list of good abrasion resistant materials follows, but their rankings change with speed, weight (pressure), and nature of opposing surface.
PE
UHMWPE
Xlinked PE
polyurethane (PU)
nylon (PA)
acetal (POM)
polyester (PET)
PTFE (Teflon)
Various fillers like graphite, MoS2, mineral (whatever that means), glass fibre, bronze, carbon fibre, aramid pulp (Kevlar), ceramic (whatever that means).
If it is melting and burnishing locally at the high load points, look for a material with a higher melting or softening temperature.
If it is cutting, look for a harder material.
Contrary to the above, sometimes the ability to bend a little to share the load before cutting can help. That seems to work in favour of PU.

Assuming that it is a combination problem due to cutting and melting, what would you suggest as an alternative?
The link below is a picture of my setup so you can better see what I have going on. Thank you.

It will be easier if you heat it in an oven for a few hours. The required temp depends on the type of nylon. If it's 6.6 I think about 180 deg C should do it.
It probably will if you immerse it in water at about 60 deg C for about a week then boil it for a few hours.
