    Used to use similar wearbars to build up the front side of subsoil rippers that ran in hard packed sand, they really wore well.

    If only you just drip chocolate on the skids for wear protection. When it no longer tasted like chocolate it was time to replace it. Mind you some candy is so hard you break your teeth on it. Candy cane wear strips... I like it!

    It's like the one below. I usually have the front lifted slightly so the back end of the wear strips carry the weight but wear out fast. They get a little warm too but the track is a 1/4 mile long and 65' wide so do several miles when levelling it at 5-6 MPH. I used some UTP 711B on the high carbon runners but still had fairly rapid wear. I thought the chocky blocks would be easier and last longer than trying a higher chromium hardfacing rod. Tungsten carbide might be better but would be cost prohibitive if had to buy a 5KG box. Soil is sandy clay and very abrasive.

    There is a company down here that offers scraper blades with a spray on carbide instead of hardsurfacing. It may be fairly cheap to go down that road with some 1/4” bar and tack on the bottom without raising your other blades up to high??

    The candy cane sounds like the best idea....or peanut brittle. Either ought to last a while.

    Peanut brittle could work. Rock hard coating with very coarse peanut matrix. Not good if you have a peanut allergy.

    There is a place by the name of Ford Steel located near Pittsburgh, Pa. That is where I get mine from.

    How does it compare with hardfacing?

    They have the chocky bars. Way better than hard facing. I put some of the bars on a dragline bucket 12 years ago. You can still read the logo and the part # on them. Definitely worth the investment if it is a high wear area.

    Have you tried Hardcro63 from ARCTEC. Buildup a cushion of ARCTEC 60 first and then some 63 on top . The 63 cracks to relieve stress but wears really well . Used to build up Churn drilling bits with it. In saying that ,those chocky bars do look pretty handy

    Would wear tile be an option? Havent tried this in anything but i hear it is a long term solution to any wear. It cannot take large rock impact or it will shatter. Guys tell me if we do this once it will last the life of the machine.

    We tried the spray carbide on excavator teeth. It was fairly cheap. Our typical life expectancy on j450 size teeth is about 2 weeks. The spray carbide added a week. We have been buying cat, esco, Hensley, or romac teeth. Blackcat would only last 1 week.

    We have been using rubber belting in hoppers that would wear hardox out in about a week. Real cheap solution. The belting typically lasts 5-6 months.

    Very high wear area. Doing 5 or more miles at a time at 5 MPH is a lot of abrasion. I think I only need the chocky bars for the rear of the skids. If I recall they are about $35 or so for the smaller ones. From what I've been able to find, the chocky bars outlast hardfacing by quite a bit and are real simple to install. I'd just cut off the back 9-1/2" of the wear bar and weld the chocky bar in its place. Hardfacing isn't difficult but is time consuming and I'd have to build up the existing skids to size before applying the hardfacing in a couple layers. Don't think rubber would work on a skid constantly sliding on the ground and wouldn't be very slippery. In a hopper I could see rubber working as long as it didn't get cut from sharp material. The hard surface on the chocky bars is about 9/16" thick so is quite a bit thicker than you could do with hardfacing. Black Cat are cheaper teeth but I'll see who all carries the chocky bars. The chocky bars all look very similar looking at the specs. I think they are worth a try.

    Do you have a picture of where you would be placing them? And dimensions?

    We use them all the time on excavator/front shovel buckets. What do you need to know..?

    They can be placed anywhere and apparently last 3 to 6 times longer than AR500 plate. In post 5 there is a picture of the landplane I think they would work good on. Just seeing if anyone has experience with them compared to hardfacing. They are quick and simple to install. I'd need some about 1" to 1-1/2" wide.

    Titan Supply about 10 minutes from where I live can get Hensley chocky bars. The CB40 (40mm wide) were $18 each so a I ordered a couple to try out. I think they were about 1/2 the price from where I originally saw them. Will take about 2 weeks to get them but I've probably got 2 month's before the snow is gone to use them.

    I use chromium hardfaced bars that I order from IMPCO in Madisonville, KY. Ask for Barry - he's the one that turned me onto this stuff.

    3/8 on 3/8 will be 3/8" chromium carbide hardsurface on top of 3/8" hot rolled plate. Several thicknesses are available. The hot roll is easy to weld on and the chromium layer seems to last forever. I use this stuff on the skids of my cutterheads and internals of the heads. I have yet to wear through any portion of the hard layer. Even when working in a rocky county, places where I could watch the skid "evaporate" a little each day, the chromium bars just stay shiny and show no wear.

    Great thing is, these parts can also be bent or rolled to some extent. I know they come from a mill in Alabama and they stuff is not cheap, but it sure is cheaper to do it once and be done for a decade.
